Currently in the process of installing a 440 Mhz Repeater at 443.325 on a water tower. I bought this site from an existing plumbing business that no longer used it anymore and wanted to relinquish it and make alittle of their money back.
The site is using 7/8" Hardline about 160 feet worth going to an antenna at the very top. The antenna appears to be a Comet GP-9 or comparable to a Diamond but no one can tell me as that info is MIA.
There are two antennas on this site, one is for the road department on VHF ( which I installed a new repeater for narrowband for them and works great w/ 50 miles coverage range by mobile) and then my antenna...
Both antennas are crooked but one is far worse than the other one on the tower. Just by looking from the ground it appears there is no type of railing on the top that I could mount a better antenna too other than 2 little stubs that is there for the 2 fiberglass antennas currently in the air.
I have checked all the settings from the ground involving sensitivity of the repeater, the tuning of the repeater and all that.
The analyzer says 1.4 SWR on 443 with the current tilted antenna.
I have access to a DB-410 antenna but was curious if they make a mount that I can secure to the vent at the very top or could I mount it to the ladder rail of the water tower? I'm currently waiting on the city for their "understanding agreement" to see what they will allow me to do with it.
Any help would be greatly appreciated in regards to a mount that either mounts to the rail or secures to the vent or will allow me to mount my antenna securely.
