Thanks guys. Actually I got VOOM installed last Friday and the installer
"Dishconnect" brought a wineguard GS1000 and just picked a location
on outside roof railing and installed it saying it'd be a good place
but told me I'll have trouble due to trees and a building etc.
I live in South SF bay area where I should be getting SF Sutro tower
stations. (about 30-40 miles). But to my dismay I'm only getting 1 station
ch 48-2 NBC from San Mateo area. Last night I borrowed a Silver Sensor
indoor antenna from a friend, removed the diplexar from the VOOM box,
and hooked the silver sensor up indoors. As I suspected I'm getting
almost all of the Sutro tower stations with proper aligning, although with
some picture beakup. channel 48-2 which I get from the rooftop wineguard
comes up no breakup no matter where I placed the silver sensor.
Seems to me like either this guy didn't align the wineguard properly
or it needs an upgrade. What do you guys think I should do ?
