Link? There's no radiation pattern or gain info for the 220 that I could find.traumacop said:You obviously have nothing to offer on the antenna. To learn a little, click on the link and read some technical specifications.
Gain over? An isotropic? Their advertising budget?It shows gain in the UHF segment.

The antenna is clearly a 2/440 (maybe 220?) vertical radiator with a very small ground plane. Probably radiates about as well as any 2/440 mobile antenna for half the price. Diamond makes some good antennas, but they also make some hype.
Anyone have any recent experience. considering purchase to use as a roof top antenna as I have limited space.
I use 2 Icom-AH7000 discone and i tested it againt the Diamond-D150/Comet-DS3000 and they all the antennas are 8 metres high and they dont even come close on performance compare to the Icom and using 20 metres of Belden-9913 low loss cable.
