Choosing VHF or UHF LP Broadcast Signal

Post by NOYB »

For a station that broadcasts on both VHF and UHF (low power).
What are the pros/cons/trade off considerations for choosing which broadcast signal to use?

VHF channel 8:
Signal Strength: 96%
Signal Quality: 98%

UHF channel 23 (low power):
Signal Strength: 70%%
Signal Quality: 85%

Obviously signal strength and quality are better on the full powered VHF. But isn't VHF more susceptible to interference?

The towers are about 17 miles line of sight. Receiver antenna is an indoor 13" bowtie wire antenna (sweet spot placed).

If those numbers are stable, and given how close you are to the tower, there probably won't be any difference between which station is used. Anything above 60% for both strength and quality will make the HDHomeRun happy, and there's enough redundant data in there where it will produce a perfect picture.

Yes the numbers are stable.
Windows Media Center (Windows 8.1) defaults to the UHF signal. So I'll probably just stay with that.
Thanks.

P.S. The tower proximity is nice. Well placed simple little wire bowtie antenna gets all the full power broadcast signals at >=95% SS; >=98% SQ (7 phy / 38 virtual chs.). Even manages to pull in, by a whisker (quite a bit of pixilation), a low power UHF 26 signal from 29 miles LOS.
