The antenna I made after reading this works better than anything else I've tried.
Kula, Maui, Hawaii 96790. We already had a statewide digital switchover, and the 5 big local stations are all now re-broadcasting on Maui in HD as well. We are 12 miles from the new (re)broadcast towers. My son and I built our own TV antenna and it works like a charm from up in our attic. We added aliminum BBQ trays to form a reflector surface at the back.
The two UHF channels work best (NBC and CBS). The VHF channels work with our antenna also, but not as strong.
Here are the signal strength readings, including the inferior results from a GE "Millenium" UHF loop/VHF dipole antenna:
Station - Rabbit Ears - Homemade Antenna
KHNL NBC ----75------------------100
KHET PBS ----66-------------------84
KGMB CBS ----66------------------100
KHON FOX ---57(drop-outs)---------73
KITV ABC ----60(drop-outs)---------72
The OTA NBC HD channel is a godsend, since Dish has not carried it for years.
I not only finally have the much-sought NBC HD channel, but am also utilizing the third tuner in my 722. Yahoo.
