Re: [Repeater-Builder] Low Power VHF Repeater - Solar
go with Lo band, way good coverage, lo band maratracs are in abundant supply, 50.00 or less, no repeater to mess with .. lo band would work well. ymmv mac/mc w5mc - Original Message - From: tahrens301 To: Repeater-Builder@yahoogroups.com Sent: Wednesday, August 26, 2009 9:42 AM Subject: [Repeater-Builder] Low Power VHF Repeater - Solar A friend of mine who is the foreman for a large ranch asked me about providing radio coverage. As there are a couple of hills (2000' AGL) around the ranch, coverage in some places would be spotty, so a repeater on one of the hills would be the best solution. However, there is no power available, so a solar/wind power solution would be necessary. (we get a lot of sun here!) I've done a couple of solar projects, but this needs to be pretty much commercial quality, so I was wondering if there is a commercial repeater available that would be a good candidate for solar power. I figure the RF power out could be 5 watts or less and still give good coverage throughout the ranch. Thanks, Tim

Tim, Is this a business band thing they are looking at, or can a GMRS repeater be a solution?

RE: [Repeater-Builder] Low Power VHF Repeater - Solar
Tim, A low-power Motorola R1225 transceiver (1-10 watts) is ideal, since it is full-duplex and contains the controller and IDer. Add a suitable duplexer, a 90-watt solar panel, a 200 Ah AGM battery, and a good solar charge controller, and you're good to go for less than $2,000. I put up just such a commercial system almost 7 years ago, using the higher-power (25-50 watt) R1225 and larger panels and batteries, and it ran 24/7/365 until just recently when I upgraded to a 100-watt MTR2000 and a more powerful solar system. The R1225 is now on standby as a backup system. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of tahrens301 Sent: Wednesday, August 26, 2009 7:42 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Low Power VHF Repeater - Solar A friend of mine who is the foreman for a large ranch asked me about providing radio coverage.
