Installed a new roof mount Radio Shack VU-120XR VHF/UHF/FM antenna, have
stunningly clear VHF, but zero UHF. We are within the UHF range of the
antenna, have a clear line of site to the broadcast antenna. We live on
1,000 foot elevation hill in Palos Verdes, California, and can see Mount
Wilson (where the broadcast towers are located) less than 60 miles away.
I have checked to see that the antenna is pointed the right direction, no
inline splitters, using good 75 ohm cable the full length, cross over wires
are not touching, UHF/VHF isolation network parallel to main boom, all
elements fully extended, etc.
I replaced the previous cable system with this antenna (using the same cable
lead in), and previously was getting channels in the UHF band.
I am stumped -- any ideas? Thank you.
