Comet CA-2x4MB (Obsolete in case anybody asks)
The gain was given at 4.5dbi on 2m
and 7.5dbi on 70cm.
Lenght is 59 inches.
Mount is a Pl-259 type. It is a ground independent type (no ground plane required)
The bandwidth seems to be wide enough to also use it on MURS and GMRS. I checked it using a RigExpert AA-1000 antenna analyzer using the SWR
