Antenna best reception not in front

Thank you for the new TVFool signal report. When I asked you where you got the elevation for your location, you were able to double check the information from Google maps. I'm confident that this report is for your location.



As before, WFIE NBC is listed on the rabbitars.info report:



I don't see WTVW causing an overload problem on this report, and what you said about your reception results with the Televes antenna with the preamp ON makes sense.

The problems with WVUT are:
1. It is a very weak 2Edge signal with a Noise Margin of -12.0 dB
2. Only 12 kW out of 57 kW ERP is sent in your direction because of the transmitting antenna directional pattern
3. You are in a dead zone for its signal coverage
4. WVUT has adjacent channel interference from W23BV on channel 23 that is 61.3 dB stronger. A tuner is not expected to reject adjacent channel interference greater than 33 dB, but the fact that W23BV is in a different direction helps



You have some strong local FM transmitters that might interfere with VHF-High channels 7 and 9.

This is the WVUT terrain profile showing the increased elevation at your location, but that last big hill is in the signal path:



You are on the extreme fringe of coverage:



raising the antenna does this:
80 ft 1Edge NM 1.0 dB
140 ft LOS NM 15.0 dB

As you said, "Higher is better."

The only solution that I can think of that has a chance of improving your reception of WVUT would be a separate UHF antenna like the Antennas Direct 91XG or Solid Signal HDB91X at a greater height with an Antennas Direct Juice preamp. Both of those antennas have a tilt feature that would allow the front end of the antenna to be tilted up to catch the signal coming down from the crest of the hill; it often helps.

I have not experimented with tilting the front of antenna up for improved gain over hilltops as of yet. I think going with a antenna with a narrow beam path would probably be the best to start with. I did notice that most antennas that I have looked at their specifications seem to vary beam path width depending on frequency. So for now I need to do some more homework!! Thanks for all the info to help.

BTW Rabbit I did check and I see that the Televes antenna we have been discussing does have the option to tilt 5 degrees but I don't know if that is enough to do any good or not? It may not be the right antenna for that being it is vhf and uhf?
