Gary me and some folks at my job that are radio-amateurs are using an fiberglass antennas for years,,,,,at least 6 years,, http://www.rfparts.com/diamond/x500hna.html
we are operating 2 systems ,one uhf repeater and one vhf repeater that can be linked with 8 repeaters on differents frequencies,,naturally ,(you need a QUALITY DUPLEXER ). all controled by home made software and hardware controler too. we shoose vertical 2 bands antenna because of space and cost,,we are 4 in my group. we can tell you that you need good grounds system because fibeglass have tendency to accumulate static and become a big condenser when the weather get wet ,,,at leats around here along the St-Laurence River. We installed at at 6 feet from a tower and a good Heliax cable LDF5. it suffer high winds and ice and never fail us . You will always have the performance you pay that is what we learn ,,even if you have 250 watts tx with no good antenna you wont go far . 73/s Gary Gervais,ve2ckn ----- Original Message ----- From: Gary Schafer To: Repeater-Builder@yahoogroups.com Sent: Sunday, February 11, 2007 12:38 PM Subject: RE: [Repeater-Builder] Combining antennas. I am not sure it included those particular antennas but at one time you could order a combination VHF/UHF antenna from DB that included two antennas on the same mast. 73 Gary K4FMX ------------------------------------------------------------------------------ From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Fred Flowers Sent: Sunday, February 11, 2007 12:27 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Combining antennas. Has anyone tried to combine DB224E & DB408 on the same mast? We have one free space on a nice tower with a good location. The 2 meter antenna on the tower needs replacing. I would like to install a 440 repeater. I have both antennas & would like to find a way to get the max use of the location. If anyone has done this, did you use two feed lines or a combiner to one feed line? I'd like to hear anyone's thoughts on this. Fred N4GER
