Thank you Bob. I will probably try your first suggestion. I had thought of
extending the antenna lead in but the RG174 going up to the antenna is kind of
fragile for extended roof lead in. A lot of branches, leaves and pine needles
land on my roof since the oak and some pine trees are about 20 feet from the
house and some trees lean in the direction of the house. The house is south of
the trees so the trees, the past 30 years have leaned in that direction. About
once a year I get up on the roof and clean "house".

Cheers

Richard
