[Repeater-Builder] Re: Lightning Damage, new UHF antenna needed
Hi John, It's on the campus of Southern Polytechnic State University in Marietta, Georgia, about fifteen minutes north of Atlanta on I-75.

The DB 404 and 408 are great antennas, however I just purchased an Antenex YDA-4404 which is a regular 4 bay dipole. It is not as heavy duty as the DB antennas but is still better than most fiberglass antennas. It is tuneable and it tends to be about half of the price of the DB as well. I think I paid around $180 for it on the web. http://www.antenex.com/index051206.htm thanks James N0QZV --- In Repeater-Builder@yahoogroups.com, "Jeff" <[EMAIL PROTECTED]> wrote: > > Hi all, > > Well, it finally happened.
