RCA ANT3036XR question
I'm a new house and few months in I'm considering getting a better VHF range antenna to swap out the DB4e I have up with VHF add on since the UHF range is cover sufficiently by the Solid Signal HDB91X. I cant seem to find a listing for the separate VHF/UHF distance range just a 65 mile general, does anyone know the specs on this? It's on sale for $60 this week at Menards so this makes it a tempting replacement.

I think that you can improve your VHF performance and save some money by using a Stellar Labs 30-2476 VHF high-band yagi instead of the RCA: It only does VHF, and can be added to your existing stack far more easily. The 30-2476 should outperform the RCA on VHF channels 7-13, and only costs $34.99 plus shipping.

With a rotator, you should be able to get all the Detroit stations, too.

The only reason I mounted it forward is because the instructions show the mount there. And that's how it ended up on the mast. I know I thought the same thing later when I looked at it. And the funny thing is the ad picture of it shows the clamp between another set of elements than the instructions show.
Mine should probably be mounted even. I don't know if there's a rule on that or not. It may not matter. |

I understand it ships from another location than their regular antennas.. However, I believe the VHF add-on kit is barely a compromise. Even the Tech Guy said anything more than 35 miles his risky with that antenna meaning the VHF add-on kit. I think the 30 - 2476 will open up New Horizons for you. It is a clean-looking antenna and well-constructed. Also during another conversation I had with an antenna Tech Guy, he said that when there is nothing they can do for their customer about VHF reception they actually recommend the 30 - 2476. Even though it is made by another antenna company. |

I mounted pretty similarly with the HDB91X on top using the Stellar Labs UHF - VHF Antenna Combiner http://www.mcmelectronics.com/produc...-2230-/33-2230 this was a pain as the combiner case would not contain the high quality guarded cables I had been using due to the heads being too large for the case so I had to cut new traditional cables with twist on heads to fit the case. The end result so far is that 2 is rock solid, not a single dropout since I scanned in the afternoon until I pointed east to get 24 Toledo around midnight, 9 was less good, only could get with a direct point (whereas a general ch 50 point will do) with a lot of breakup, the UHF reception has been pretty disappointing, I'm really hoping its the weather as its been storming in Detroit today but tonight (prime reception time) I scanned under 20 channels (poor in any weather) 20 & 7 haven't been seen at all & 4 ,62, 56 are only seen intermittently with lots of breakup, I thought in the first couple hours that ch 4 "seemed" rock solid & I was expecting it to stay. I was hoping for improvement with the height boost of the HDB91X but perhaps the DB4e was doing more than I thought when I consider it to be UHF overkill, it always was a very impressive antenna, I got the HDB91X for a more directional point but I'm not sure if it tops the fringe reception, I would hate to have to remount again soon as that was more of a pain than expected but if things don't improve something will have to change. https://drive.google.com/open?id=0B2...m5pQzM4Y3BicE0 |

That is a nice combiner. http://forum.tvfool.com/attachment.p...1&d=1475237536 For about $14 more there is a RCA PREAMP1R available and it is a great UHF/VHF combiner. I used it to combine my UHF VHF antennas. it has about 20bd boost and lower noise. There were some issues reported a while back, but I haven't read anything lately and both of mine work well: ttps://www.amazon.com/RCA-TVPRAMP1Z-Preamplifier-Outdoor-Antenna/dp/B003P92D9Y/ref=sr_1_1?s=electronics&ie=UTF8&qid=1475238081&sr=1-1&keywords=RCA+PREAMP1R That preamp couldn't hurt looking at the distances you are working with... Anyhow, I hope one of the experts can offer some help here for you. |

I'm limited to a preamp designed for powering by +17 VDC at less than 50mA using a single cable connection in conjunction with the Eagle ROTR100 I'm not sure if that one will work, I'm presently using none, I have a Juice but its incompatible, I'm not sure which ones are, I wrote the company for suggestions. |
There are exactly ZERO current preamps on the market that are compatible with the ROTR100's One-Cable system. The RCA is NOT compatible with it. FWIW, I suspect that feature wasn't even enabled in the product the last time it was manufactured back around 2011. I tried several of the rotors with amps that met their specs and none of the rotors would work with any of the amps
Run two cables, there is no alternative unless you can find one of the really old CM or Winegard amps that were supposed to compatible with it. |

I'm sorry I did not realize you were running a one wire rotor system. Personally, I would run a separate cable. If it were me, I would be trying it a different idea like some sort of pre amp system...I hope one of these other guys chimes in, maybe someone has a better idea... I would like to see you succeed, I hope you can figure out what is wrong with your system. I guess possibly you could get a larger antenna like a DB8e for your UHF. |

but though the gain is listed at a high 18dB from what I've been reading its being said to be a lessor of the HDB91X, I'm not sure if that is bias, personally in my experience the HDB91X has been a lessor to the DB4e (with the exception of receiving ch4 slightly better, the goal of using it, though the loss in 0 reception of ch20 & ch7, even at night presently, among others is not worth that.) If HDB91X is the best, as claimed, for fringe UHF I'm not sure where to go, it hasn't been my experience, the DBs are claimed to be "ideal for suburban and rural areas where heavy foliage or roofing materials reduce the incoming signal". this is certainty my circumstance so perhaps that's why it outperforms. I actually have the lessor Solid Signal HDB4X, so I could conceivably jimmy together with the DB4e for a equivalent of the DB8e but I think that is rather top heavy for that stack, I would hope for a single UHF antenna solution ideally. |

http://www.solidsignal.com/pview.asp?p=149881 It is on sale right now. It has a variable strength pre-amp. I already know, you don't want a pre-amp, but you can use it without and it is there should you need it and want to run separate cable to your rotor. Quote:

AD Tech has done it with an 91XG and picked up some gain, but it was minimal. Quote:
The Winegard HD7698P is a one antenna solution for UHF and VHF, but it is highly directional. And in the $130+ range + shipping, so that's out I'm sure. So is that Televes DAT709 LR Mix, which is available without VHF (minus the "mix") |
Did you ever try an FM filter? Your local FM transmitters are even stronger at your new location and might interfere with VHF reception of 7 and 9.
http://www.fmfool.com/modeling/tmp/9...a/Radar-FM.png WWWM-FM is 64.1 dB stronger than WJBK and 68 dB stronger than CBET. |
Quote:
WJBK has been rock solid, zero break up all times of the day up since the 30-2476 install, even w/o the preamp, 9 is better post preamp with slight break up. |
Glad to hear you tried the preamp. Was this all done with the HDB91X & 30-2476 ?
How did you combine the two antennas, with MCM combiner still ? Also, I am assuming you are using the "real" channels numbers, not the virtual number, it appears to be the case. |
