New to OTA, looking for advice

[mikeyfrog]

Yeah its probably UHF vs VHF. I forget what antenna you are using. Some antennas that are combo units (VHF/UHF) are more emphasized on UHF and the VHF is kinda "an afterthought" with range not as strong as UHF

Winegard HD7694P, RG6 into the media closet (maybe 30 feet worth).

 

[Mr Tony]

those VHF stations are about 150 degrees opposite the rest of the stations. It shows 27 degrees which is NNW of you whereas the rest are dead south
What happens when you aim the antenna NNW? (the backend facing that way)

That is the way i've pointed it. The austin stations come in anywhere from 75-100% on the tuner meter from the backside. I can receive 3 other waco stations (real channel 26, 44, 46) and 1 bryan station (real channel 50, which is 2 edge 100+ miles, hits around 72-75 on the signal meter!).

Anything you think I can do to get the other 2? Really appreciate you taking the time to help out.

 

[Mr Tony]

so I assume you get no signal on those?
With numbers that high on the tvfool the only thing I can think of is the antenna is too small (The VHF portion) to get a stable picture. You can do one of two things
-you could get a pre-amp like this http://www.rcaantennas.net/search/?sku=TVPRAMP1R
That is the one that a few of us use here and it works great
-a larger antenna. You can get a VHF only antenna and combine it with the existing one. MCM Electonics has a good VHF only antenna

Can't really see if i get any signal, its just not high enough to register on the autoscan. Might try the preamp route. If it doesnt work, at least I get all the austin channels. Thanks again Iceberg!

 

[Mr Tony]

the pre-amp can be bought at alot of retailers (so if it doesnt work you can always return it)

Shocked I can get the 2 edge 100 miles away but not the LOS KCEN and KWTX at half the distance. Any thoughts from the experienced guys on here?

Don't think an amp will help this problem
KCEN on real channel 9 is Adjacent-channel with KWTX on 10
They may be 'washing' each other out. (Interfering)
(wonder why the red "A" isn't shown here?)
(just wondering - wonder if a notch filter could make one or the other come in????
Channel Eliminator?http://www.tinlee.com/CATV-ChannelEliminators.php?active=1
Maybe one that's switchable, notch out 9 or 10, receive the other. Find a HAM, could possibly build one.)

Adjacent channels are permitted with digital TV, as long as the two are in the same general area, which KCEN and KWTX are. They should not be interfering with each other.

i did a post here back in the day on multiple antennas you will need a combiner or use ultra low loss 300 ohm wire connected correctly then run the coax. as for vhf uhf sometimes i skip the vhf if there is not enough stations to justify a combo antenna purchase and get a bigger than needed uhf. swr is not important for receiving a signal you just wont get as much gain.

I was just going to post that. Here in Minneapolis we have
32 CBS
33 3ABN Low power
34 PBS
35 ABC

16 & 17 are both low powered too

well that depends on the market. Here in Minneapolis FOX & NBC are on VHF so its a necessity really
