First I know zero about electronics but I got a quote of over $400 for an antenna set up from a national vendor and decided to look around some more. I came across this site Gray Hoverman Antenna build and it seemed easy enough so I built it. It works but I think perhaps it can work better if I add the right parts. I filled out the questionnaire.

If in Attic, Roof or outside separate Mast/Pole:
How high above ground is your Antenna installed/proposed:
._18 ft.

Do you have an Antenna Rotator:
(Make/Model/None): no

I get a good signal but a few stations fade in and out. I can get channels 2/4/7/11/16/38/. 7, 11. 42 tend to be inconsistent.

agassiz,

My antenna survey is similar to yours, with stations at four different compass points. I have tested a dozen or more different antennas here including a 16-Bay Hoverman at about 15 feet above ground level but I ended up using a Channel Master 4221 4-Bay with an antenna rotor mounted about 28 feet above ground level. In many situations antenna height is more important than an antennas 'gain'.

Hoverman antennas are quite large and the home-brew example on that website would require a very sturdy mast or tower to support it during a windstorm. You might have better results using a smaller antenna such as an 8-Bay or even a 4-Bay if you could raise it higher than 18 feet. Is it possible for you to mount a much smaller antenna significantly higher?
