Normally, mobile antenna gain is referenced to a quarter-wave whip on a metallic roof for a ground plane, where base antennas are referenced to a dipole, which is different. I forgett the exact number, but a diploe is something like 1dB above a 1/4-wave GP. A lot of amateur-grade antennas are referenced either to a 1/4-wave, or worse yet, an isotropic source, which is a theoretical point-source antenna. A dipole is about 2.1dB over an isotropic, I think. -- Jim Barbour WD8CHL Yahoo!

Re: [Repeater-Builder] Repeater-Builder antennas and other products
My experience, My first VHF repeater on a really big tower and I installed one of those "high gain dual band base/repeater antennas." Well static desense finally set in after a couple months, so I decided to purchase a commercial grade DB products antenna for my ham repeater. I think the ham antenna was spec'd at 7 db gain and the commercial antenna was an honest 3db gain DB 222 I think. Well, I had to finally take down the ham antenna before the new one arrived, fiberglass was full of water, and so I mounted a quarter wave mag mount on top of the building at the base of the tower while I waited for the new antenna to arrive in a few weeks. Well the quarter wave antenna preformed almost as well as the dual band up 175 ft higher. When the new antenna arrived WOW, what an increase in performance. One of the local ham guys (works at a Moto shop) had always preached to me about commercial grade antennas and was he right. Never again, I sigh every time I go work on some of the area ham repeaters from the local ham clubs and see the antenna system. The argument usually always gets down to, well it has higher gain. A quick question of how do you check for desense and that is where I usually stop talking, at that point it is useless. So ham antennas for repeaters, been there did that, not doing it again.
