Using the custom filters approach has limitations. If you want a lot of channels, you would need many custom filters, and they would have an insertion loss that would affect the weaker channels. Also, there are limitations with adjacent channels. A notch filter for a channel will affect the adjacent channels. Don't forget, many TVs can edit out a channel you don't want by going into the channel menu. If you want just a few channels from one direction to add to the coax from the main direction, you could add some tuners and modulators to insert them in unused UHF channels. They would be analog and not HD digital, but analog can look better than compressed 480i digital. https://i.imgur.com/ly36iue.jpg Analog can look better than this compressed 480i digital: http://i.imgur.com/MMKlm90.jpg The method I favor for your situation would be to run two coax lines to each TV, one for each antenna system. At each TV there would be an A/B switch to select which antenna is desired. If the TVs are not able to add a channel after scan, it would be necessary to rescan after changing direction. To avoid that, you can connect the main antenna to the TV antenna input and connect the other antenna to a separate tuner with its output connected to the TV aux input. With HDMI it could be HD. |
Well thank you rabbit and the channel master rotors are junk!!
And so I experienced the same problem with the RCA.Rotor That is why yes $300dollars for a Rotor is crazy to spend. But you do not have that problem when installing a good quality rotor. And with the 91xg,you need a Rotor to get IT'S full use. And the best ANTENNA for the uhf.Well good luck and be safe on the roof and look out for power lines when installing an Tv ANTENNA. |
Yes u might want too see if the low power vhf channels
Or maybe like the fcc suggests use a combination ANTENNA That does Low&hi,vhf/uhf,with a good quality rotor That will last year after year after year. And if you use a channel master amp it does the same thing And you are not loosing db,insert loss,and it's fm filter. |

Thanks for the advice. It looks like my XG91 got damaged this winter. The lower rear reflector is just hanging by what looks like the coax, surprisingly, the reception is still good. Now, I have to get back up the mast some how and service the XG-91. I have to say, that I'm not impressed with the XG91 durability. My HDB91X seems more solid, at least in the reflector area. The XG91 reflector is like garden fence. And not very well fastened either. I like your idea of the two coax cable to each TV, not that hard to do. But, as always, I have rethought the situation. Buying an expensive "box" to block certain signals would be a great idea, but you say expensive. How expensive? The other idea I have is … Is there still such a thing as a "omni directional" antenna? I drive around different towns doing business and I always look up at the rooftops. I still see those antennas. But, I also see a lot of 8 bays these days. Some masts have two 8 Bays usually one pointing north and one south. But what's the deal with removing the reflectors? The reason I ask is that I don't see a lot of co-channels on my TV Fool report: http://www.tvfool.com/?option=com_wr...90382eb6d5dbe3 Well, there are a few. Just rethinking the whole plan since I have to get up and fix the array. Would it just be easier to use something that is more omni directional? Thanks, Bob |

Why don't you put up an Omni to satisfy your curiosity. |
Well you should not have too remove any thing off an ANTENNA when you spend that much money on it $100dollars you should probably tack a look at the new master antenna
With its vhf/uhf and go with the channel master 7778amp check it out RABBIT!! |

BTW, your location per the chart, is ideal for one of our C4MAX antennas. Bi-directional right out of the box. I've been recommended reflector-less C2V and C4V antennas for your area along the state line for a long time with very good results. Quote:

I have a 4 bay with no reflector and receive excellent reception from front and back. Back tower is appx 45 miles out and front towers are appx 60 miles out.
I even turned it slightly off line and receive some side towers, although not was well as the front and back towers. |

Beem with of 60 marking it easier for you too find the broadcasting tower's And the price is right!!!! |

Solid Signal's claim of a 60 degree beamwidth for the HDB91X is misleading. They are not using the conventional method of calculating beamwidth. Some people will fall for it.

Additional gain comes from making the antenna more directional with a narrower beamwidth, which ignores other directions like a searchlight or spotlight. There is no free lunch. |
C4max ?

I haven't had the chance to see how bad the damage is to my XG91, I just see the reflector hanging, I guess by the coax? So far good reception. http://forum.tvfool.com/attachment.p...1&d=1552623615 I'll look into the C4MAX. They look like the windload is low. Funny, I was driving through Kenosha WI, I saw this array: http://forum.tvfool.com/attachment.p...1&d=1552625490 I know it's not the MAX, but someone got crafty. Actually, I've seen a few of these array near the state line as you say. And, I thought I saw two C4MAX's combined, somewhere. Easily distinguished by no reflectors, correct? I always thought they were novelty antennas and overlooked them. |

I have to admit, I did mean Bi-directional, not Omni. I don't know why IO asked about that, the only time I see them is on RV's actually. My bad. I was thinking Bi-directional. |

Thanks for the new photos. Please let us know if you make any improvements. There is one thing I don't like about the Solid Signal Xtreme Signal HDB91X. The coax connector on the balun doesn't make good contact with the center conductor of the coax; it doesn't grasp the wire firmly. I noticed that when I was making resistance measurements of the driven element. I consider that a design defect. I inserted a short length of 18 gauge wire in the connector to make the measurement, which is the same gauge as the center conductor of RG6 coax. https://forum.tvfool.com/attachment....5&d=1552676755 https://forum.tvfool.com/attachment....6&d=1552676901 https://forum.tvfool.com/attachment....7&d=1552677078 https://forum.tvfool.com/attachment....4&d=1552657281 |
Well you see that is why I went with the HDB91 instead of the antenna Direct 91st
And the HDB91 has the same performance as the 91st and I like your set up But know you need too tack it down and see what happen to it Don t for get IT'S life time w tee.And if you get 2antennas together on top it will look a lot better than just One antenna with your hi band vhf ANTENNA |

Had a lengthy post underway earlier today but my my 2 month-old Dell desktop decided to crash on me with a BSOD and a memory error... so, you get the short answer this evening.
Anyway, the 91XG, like ALL of our antennas, has a lifetime warranty (try that with the Chinese-made stuff to which it has been compared). All customers need to do is contact us, the link is in my signature. Have a great weekend! |
Quote:
Yes, I am listening to the whole thread here. The 8 Bay idea has me very interested. Your pattern tells me that it could be the answer. A while back, I saw a 4228 double stacked in this test, can't find it right now,. AD Tech suggested the C4MAX. Have you done any testing with the C4MAX? One advantage would be the lesser windload, at least that's what it appears to a layman like myself :) Also, I guess my XG91 is a lifetime warranty, that's good. I may warranty it and save it for other uses. The balun issue is interesting to me. in the automotive industry, that causes major issues. Also known as pin fit. |
Well the warranty is good On the antenna Direct 91xg.
I just dount like to return to some one that I have installed An ANTENNA that has been up for a year later And the public mad about an ANTENNA falling apart that I suggested to someone!! That is why I have used both of these antennas Direct&the HDB91. That has not let me down and it's been 5years on the first one I have Installed and China yes just like the car's performance BETTER than the USA grade. |
Questions for ADTech
Quote:
AD Tech, what would you say the wind load is on these C4 / Max antennas? So, the C4-V-CJM, I have been researching/reading. AD says it's re-engineered from the original C4. What did they do to improve it? I imagine it has to be better, since its more expensive even without reflectors :) Also, you mentioned that it is highly recommended along the WI-IL State line, that must be true since I see a lot of them. I should clarify. I see a lot of the the C4's with reflectors, usually aimed in opposing directions. http://forum.tvfool.com/attachment.p...1&d=1553561360 Wouldn't they have been smarter to keep both and remove the reflectors? or even just one? Or, is the original C4 useless w/o the reflectors? My experience has taught me that it's a bad idea to combine antennas pointing in two opposite directions. I found a decent price for the C-MAX on Amazon, ($120.00) so I was thinking about purchasing one or two. It also appears they still have some of the original CS4Vs with reflector for $109. Would that be a better deal? Thanks, Bob |

Thanks for the quick reply, it's well appreciated. No wind testing, surprising. They do appear to be very weather proof though and somewhat aero dynamic, especially with the reflectors removed (as designed). So, here's where I saw they have been "re-engineered", according to Solid Signal's marketing Dept. of course: http://forum.tvfool.com/attachment.p...1&d=1553863874 Attachment 3336 http://forum.tvfool.com/attachment.p...1&d=1553864120 Attachment 3337 I've seriously entertained the idea of getting two. While reading reviews o Amazon, I did see where some complained about the VHF capabilities (over 35 miles). If one was so inclined, could two of these be combined to one input? |
Above the antenna video. Scared of heights?
Quote:
Hindsight being 20-20, I think I would have done a nicer job on the video. But then again, it kind of shows the perspective which is what I wanted. In the video the antennas are actually pointed opposite of the way I normally have them. In the video they're pointed at Milwaukee actually. That's to say that Chicago is directly behind that tall fresh green maple tree opposite of the point of the antennas. That tree is gotten substantially larger by at least four or five feet I think. Still, reception has been good with the XG 91 even with the reflectors still hanging and the 30 - 2476 is kind of a waste because we only have one VHF High channel in Chicago. But you're right, it does put you right up there with the antennas and even gives me that queasy feeling because I'm somewhat afraid of heights. I have a difficult time looking down when I'm up high, even the video gives me that feeling! |
Solid Signal's write-up appears to be their in-house doing. I can see multiple errors.
Yes, multiple antennas of the same type may be connected following certain rules and with due consideration of the capabilities of the antenna as well as the desired result. VHF reception via a simple dipole is always going to be a compromise and includes several factors outside the control of the device. The incorporation of a single dipole is a compromise driven by the need to have a very compact antenna that fits in a box smaller than a briefcase so that big-box retail stores will actually put it on their shelves. The alternative is a much larger antenna such as our C5 or conventional stick antennas. Outside of the home centers, you won't find either of those types of products available in-store at any of the national retailers, you'd have to special order them. |

AD Tech question
2 Attachment(s)
Hello and Good Morning AD Tech.
If there's really no difference between the C4MAX and the CS4V, wouldn't the old CS4V be a better deal ? (At least at Amazon) http://forum.tvfool.com/attachment.p...1&d=1553867169 http://forum.tvfool.com/attachment.p...1&d=1553867267 When I scroll through the pics, the main difference (I see) is there appears to be casing over the middle frame. Is that for weatherproofing? The other difference (I see) is obvious. The reflectors are on the CS4V, should I ever need them. The price difference is minimal, but when you add on the reflector kit to the C4MAX, it's greater. Your opinion (and other's as well) is appreciated. Thanks, Bob |

I'm trying to figure out a way you get good reception from Chicago and Milwaukee at the same time for one or two antennas. The reason I'm looking at the C-Max series is because they are bi-directional and they were recommended by AD Tech.
I'm reading everybody's advice do you have any other good advice? I haven't bought any antennas yet. |

Me ALL new right down to a new balen,free of charge where did you buy your 91xg if it is a truei antennas Direct 91xg call them directly becuse I bot my in at solid signal you have the best ANTENNA for your needs call them and ask for your parts on the 91xg. |
