New antenna missing wanted channels
Hello, I talked to an assistant at Solid Signal and they sold me a HDB91X. I told them I wanted the channels 50 miles to the south, and they said this was the perfect setup.
Now I was able to intermittently pick up one of the channels. The antenna is above my roof line, but it does aim right at a maple tree and about 100 feet away in the same direction is my machine shed. I am picking up about 25 other channels with no problem. Any Ideas? Thanks! http://www.tvfool.com/?option=com_wr...9038acdfbc354b |
Hello, upks
Which channels that you want are missing? |
KHQA-DT and WGEM-DT.
|
Both of the stations cited are VHF. You were sold a UHF-only antenna which would certainly not be expected to get them.

It is the real channel number (also called physical channel or RF channel) that determines what antenna is needed. VHF-Low, real channels 2-6 VHF-High, real channels 7-13 UHF, real channels 14-51 The virtual channel number (like 5.1 or 5-1) is a holdover from the analog TV days to maintain the identity of the station, and is what the TV displays. By convention, the virtual channel number is given in the decimal form to keep it from being confused with the real channel number. The Solid Signal HDB91X is a good antenna for UHF channels, but it is a poor antenna for VHF-High channels. They gave you bad advice. https://www.solidsignal.com/pview.asp?p=hdb91x Their title says: Quote:

http://forum.tvfool.com/attachment.p...6&d=1529768349 Maximum gain 23 dB? I doubt it. It's hard to believe what they say, because it comes from the marketing department, not from an engineer. You need to add a VHF-High antenna and combine it with your HDB91X using a UVSJ UHF/VHF combiner (AKA Diplexer}, or replace your HDB91X with an antenna that will get UHF and VHF-High. VHF-High antenna, Stellar Labs 30-2475: http://www.newark.com/stellar-labs/3...vhf/dp/48Y8141 a little more gain, but bigger, Stellar Labs 30-2476: http://www.newark.com/stellar-labs/3...vhf/dp/71Y5462 UVSJ combiner: https://www.antennasdirect.com/store...Combiners.html or a UHF/VHF combo antenna to replace your HDB91X: Winegard HD7698P smaller version with less gain; might not be big enough: Winegard HD7694P The least expensive option is to add a VHF-High antenna to your present antenna, but you would have two antennas to mount. |
Yes so true Rabbit so call solid signal and tell them that
And they will switch the 91 for the uhf/vhf winegard,Hd7698p And if nice about everything you might get free shipping Well good luck and be safe on the roof. and don't forget about Them power lines when installing an outdoor tv antenna!! |
To add an inexpensive VHF antenna to your existing UHF antenna see if you can find a Stellar Labs 30-2475. I found it listed at neobits.com. Add them together with an rca preamp-1r preamp.
|
Thanks a million for all the advice!!! Guess I should have got on here and asked first instead of trying something then trying to fix the problem.
|
Gonna show my knowledge and ask a dumb question. Is the higher gain on the stellar 2476 better in my situation?
|
One more while I'm at it. Rabbit and Nascarken both said the Winegard 7698. Would that be a better antenna by itself than the other two together?

Yes, the larger Stellar labs VHF antenna would be good. |
Thanks Tower Guy! Gonna give it a shot with the two antenna setup. What direction would you suggest aiming the HDB91X?
|
Hello there Rabbit and I think it's easier for you to get the Winegrud yes the slellar labs.
30-2475 are a hi vhf ANTENNA and I have two of them stagger stacked with 2 of The same 91,that you have of one know I will explain my hole antenna set-up and Experience,which was quite fun!I have 2 91 stacked side by side 3ft apart,with my 30-2475,hi vhf,stagger stacked when you put the two ANTENNAs meaning they Should be 3ft apart forum one another when a uhf,vhf!antennas are put together My ANTENNAS are on a 150ft tower receive of 1500miles away and the higth of the antenna makes a big improvement of your receive of channel's to and I almost forgot A good mast mount amp is better too help pull in the distance channels and too STOP Over load keep you ANTENNAs away frum your strong signals tower's well good luck with your antennas and be safe on the roof and look out for power lines with tv antennas!!! |
You could pick your favorite PBS or aim it at KYOU for a second NBC and FOX.
|
Tower Guy mentioned putting the two antenna's together with a rca preamp-1r preamp. Would this be a substitute for the UVSJ UHF/VHF combiner (AKA Diplexer) rabbit mentioned?
Just wanting to make sure I am going to order the correct things the second time. Thanks!!! |

If I lived between Quincy and Otummua, I’d put the UHF antenna on a rotator but leave the VHF antenna below the rotator aimed at Quincy. |
ROtatOR????

Top of the uhf becuse of noise with vhf,and power lines, becuse of hum.s And so on what are you looking too do and what kind of ANTENNAs are you Using? And for best results one feed line for vhf&one,for vhf,and one for UHF!! With & A,And,B,swich?and a good thick ground.!!!!!lol |
HDB,&LAB,hi,VHF

With it and buy a channel master 7777,and use the backside of the antenna When reviewing your nearby tower's BUT!! I'm not B'S ing,you I have two the 30-2475&2,of the 30-2476 all stagger stacked pushing Like 65dbg,or db I each set hi band vhf,with a mast mount vhf,AMP And yes my HDB91,stacked side by side each antenna pushing 65dbg,orDBI UHF only AMP,and IT'S only one feed line power up the amps on their o power supply of 24,VOLTS,a piece,on a 150ft tower receive of 1500miles away Cost of $4000dollars + my low,VHF,of a $1000dollars,AND I LOVE IT.RF,no c in R,F.lol |
