I went on eBay and did some low ball offers for base station repeaters. Unfortunately everyone took my low ball offers and I've ended up with repeaters and a bunch of spares. We now have one 110W uhf system for ham use and two 25w repeaters for business use. We have the antennas for all of this, duplexer and heliax. We're good to go as far as what needs to be provided for the commercial repeaters. 73's -- Bryan Fields, W9CR Florida Simulcast Group, Inc.
Bryan, Are the business repeaters UHF also? What are the models? Jerry On Wed, Jul 15, 2015 at 8:05 PM, Bryan Fields <bryan@flscg.org> wrote:

What are the models?
They are all Motorola Quantar units. They support analog FM wide band and narrow band, P25 (and Astro too). Importantly they include a 4 mhz wide preselector, and the transmitter has a built in ferrite isolator/circulator. This is very important as I'm sure an antenna terminated into a wattmeter will show at least a couple watts or more just based on all the other crud in that area. Everything is part 90 certified so in the event we need to swap parts to get something fixed we can. It's not just some spare parts we hacked up, they are continuous duty public safety units that were $15k each when new. The antennas will be DB-408 for the commercial users, and DB-420 for ham. These are 6dBd gain and 9dBd respectively. The DB antennas are DC ground and basically function as lightning rods protecting the electronics. -- Bryan Fields, W9CR Florida Simulcast Group, Inc.
Bryan, The Motorola Quantar look like they will be a solid repeaters. Jerry On Wed, Jul 15, 2015 at 9:00 PM, Bryan Fields <bryan@flscg.org> wrote:
