REPLY: Everyeone, Thanks. ITs a crankup outdoor roof mounted
Wineguard Antennae on my RV for VHF tv stations. Inside, there is a
red button which i press that feeds 12 vdc power into the coax
cable ...so....i assume THIS is the amp which came with the unit
(??). How can i pull in weak signals, better, with what i have ?
Thanks, Dave.

In order of benefit. Get a taller antenna. Get a bigger antenna.
