6 months ago all my local channels were at 100% with my 14 month old Winegard 9095 antennae ( 60 mi. ) directional. 3 months ago it began fading to no picture. Channels 4 & 5 are still 90 and 100%.....if all stations are coming from MT. Wilson 336 degrees, how do some come in and others do not ?? I've changed coax cables, hi def Direct TV receiver, 75 ohm transformer, elements are all straight. Terrain is flat with a few trees 150 yds away and have always been there. I have also moved the antennae all along the rooftop any ideas ?

The broadcasters atop Mt. Wilson differ in how much power they transmit:



KABC Effective Radiated Power (ERP): 182. kW ERP


KCBS Effective Radiated Power (ERP): 469. kW ERP


KCET Effective Radiated Power (ERP): 190. kW ERP


KCOP Effective Radiated Power (ERP): 371. kW ERP


KNBC Effective Radiated Power (ERP): 380. kW ERP


KTLA Effective Radiated Power (ERP): 1000 kW ERP


KTTV Effective Radiated Power (ERP): 680. kW ERP


Weather & seasonal changes also affect reception.

Thanks for that info but I should add a few things. Mt Wilson is 40 mi. away and my neighbor has the Winegard 9065 rated at 25-30 mi..... mine is 60 mi. He stated that his reception is about 80% and never has had a problem with the hi def. ( 2 yrs ). This has been bugging me for 3 months and have tried everything. The only thing left to replace is the antenna and everybody says there's nothing that can go wrong with a relatively new antenna. any thoughts?
