Im putting a CB in my Girlfriend's truck, and the only antenna she would accept is the through the glass antenna from Radio Shack. Wish she would go with a good mag mount, but thats all I could get her to use. My question is, what kind of power can this antenna handle? Im thinking 50-70 watts at the most. Whats your thoughts on this.

307 uses an antenna like this he swears by it! Just kidding! Sparky, I doubt it would handle even 50 watts. Shack's site says it's only 22" tall???? Doesn't even look like it has a loading coil (except for the pig tail in the middle). If you can't find any documentation try an export radio on it with a good SWR meter and see what happens.

Ahhh..the 'ol "through the glass" trick..

Actually, they work OK for stock power. I wouldn't try putting more than 25w SSB into it though. The coupling coil probably won't handle it. A buddy of mine put one on the rear window of his El Camino, running a Midland 13-882 and we regularly talked distances of 25 miles on AM, base to his mobile, over hilly terrain. It's not anything I would want for reliable communications though, not so much because of the transmit, but more the fact it doesn't receive very well. Side note: I ran the 2m/440 version of that antenna with mixed results. Great for repeaters, but crap for simplex.

just hook up a palomar 250 gold to it for 60 bucks and burn it up until it folds over then package it up and send it back with a letter attached and have it say, you just cant beat a palomar!

Yea, I dont really like the antenna. Just got it on today, but have not had a chance to run it through the paces. I tried to talk her out of it, but that is the only one she would go for. Ill keep you posted.
