Thank you all. Will try new coax cable without amp on Monday. Radio Shack antenna specs: HDTV/VHF/UHF for channels 7-69. 31 elements, 85 " boom, W x H x Turning radius: 43.5 x 23.5 x 48", impedance 300 ohms.
We have tried completely removing the amp. We have 1 TV. Not concerned
about receiving KRCW (32.1). Moisture at the transformer/F connector may
be a problem--there is no weather boot. Will inspect when installing cable,
replace F connector and seal with tape.
Thanks for the advice!
Chloe
