Multiband VHF-UHF Antennas

[SCDUG]

I am looking for a commercial quality dual band, VHF-UHF base antenna. I need something that will stand up on a tower and is DC grounded for lightening protection. Please no Japense fiberglass amateur grade sticks. I have lost three in the last six months due to lightening or wind damage.

The only one I have found so far is the DB-314 that Andrew no longer makes or will even talk to you about it.
I am thinking of building my own out of a DB-214 and a DB-408. Since I need to move the two top DB-214 elements down the mast opposite the lower elements to make room for the DB-408 elements I need harness wiring information. Anyone have the dimentions for the VHF portion of the DB-314 antenna?

Thanks

VHF - UHF Dual Band Base Antennas

Comet and Diamond antennas just will not work! I have lost three Comet GP-98 antennas in the last six months. The first GP-98 was damaged by wind, connections opened up in the base and VSWR went high on all bands. We then tried a Comet GP-15 and a CX-333 all were destroyed by lightening, fiberglass everywhere. My location is in the lightening capital of the world. We average 90 to 100 strikes a year. The only thing we have found that will stand up are the commercial DC grounded antennas.

I am in the process of building a DB-314 antenna. Decibel Products produced this antenna up until Andrew bought them out. They are no longer in production thus we are building our own.

Have you taken a look at Mosely antennas? (http://www.mosley-electronics.com/page files/commercial.htm) They are about as bulletproof as you can get in a base antenna.

Here is the problem, most commercial entities don't use dual band antennas, why would they? If you are a commercial entity that uses VHF then you buy a VHF antenna. I you are on UHF you buy a UHF antnnna, the simple answer is this if you want dual band capability you buy a VHF antenna and a UHF antenna. I just did a check and I didn't see any hits for a dual band base station commercial antenna, except for a few that have already been discussed. So it appears you need two antennas one for VHF and one for UHF. there you go btw I checked maxrad and antenex, only dual bands available, were celluar/pcs and 700/800 mHz.

Have you checked this one, it has direct ground for protection.

Previous post stated the db-314 is no longer made.

You are correct, my mistake.
