Re: [Repeater-Builder] Antennas that work both in commercial and amateur
I would have to suggest any copper that has a huge bandwidth will have gain on only one tuned area , if you do want to span such areas a broadband dummy load like a Discone might be of use or tuned sticks for each frequency would be achievable and certainly would be of value in both tx and rrx >From: Joe Montierth <[EMAIL PROTECTED]> >Reply-To: Repeater-Builder@yahoogroups.com >To: Repeater-Builder@yahoogroups.com >Subject: Re: [Repeater-Builder] Antennas that work both in commercial and >amateur >Date: Thu, 15 Feb 2007 13:36:10 -0800 (PST) > > >--- mch <[EMAIL PROTECTED]> wrote: > > > If you find one, it would have to be pretty low gain > > (like Unity). > > > > Joe M. > > > > Jed Barton wrote: > > > > > > Hey guys, > > > I need some suggestions.

RE: [Repeater-Builder] Antennas that work both in commercial and amateur
There are a number of old post on this subject. Take a look at the 4 bay dipole antennas from Antenex (made by Bluewave). VERY broadband. As for whether or not they are expensive is a matter of personal opinion.

I need a vhf and a uhf antena. Here's the requirement. I'm planning to operate both amateur and commercial stuff from the house. I'd rather not use a ham antenna in the commercial bands. Are there some that'll do the 136 to 174 split, and some UHF that'll do like 439 to 490? Any ideas? Thanks, Jed

If you find one, it would have to be pretty low gain (like Unity). Joe M. Jed Barton wrote: > > Hey guys, > I need some suggestions. I need a vhf and a uhf antena. > Here's the requirement.
