I have two 2m/440 mobile antennas for sale. First is a Comet Z780, in
good condition. The bottom section of whip was replaced with a piece of
brass welding rod. It is very sturdy and served me well for over a year
after the repair. Specs: length 62" overall, handles 150 watts, gain
(dBi) 4.5/7.2, UHF connector. List new at D&L Antenna Supply is $82.95;
asking $30 shipped anywhere in the US.

Second antenna is a Diamond NR-770HA, in good condition. Length 40",
handles 200 watts, gain (dBd) 3/5.5, UHF connector. List new at D&L
Antenna Supply is $71.11; asking $25 shipped.

Both antennas served me well for several years. E-mail me if
interested, thanks!
