Thanks for the comment to Neal about the cables. RG-400 and 142 are very good, quite common, and very reliable. If you take a look at the specs on 214 and 400 you might note that the 400 is rated att 98% shield where as 214 is at 96% for whatever THAT fact is worth….probably nothing. - Mike

I only use RG 214, and or superflex for my inter connects between the repeater, amps in line(power amp/preamps), and the duplexer. Mosly 1/4" superflex becuase I got lots of it. In a pinch I will use RG-142... Never use that 400 or 9913 garbage.. --- On Sat, 3/14/09, Michael Ryan <mryan...@tampabay.rr.com> wrote: From: Michael Ryan <mryan...@tampabay.rr.com> Subject: RE: [Repeater-Builder] 220 Repeater Power Amp To: Repeater-Builder@yahoogroups.com Date: Saturday, March 14, 2009, 12:47 AM That’s the model I am using now. I have some other issues to study before changing to another amp. But hearing that someone is using this same amp is encouraging. Like I said though, I have to check into the actual tuning of the transmitter to see if I have done something that is creating my problem. For those interested, the cables in the rack are all RG-400, no 9913 or clones, no LMR stuff...nothing else. Duplexer is Telewave 4 cans, RG-214 cabled, ½” Andrew hardline to the antenna. -Mike From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Roger White Sent: Friday, March 13, 2009 5:45 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] 220 Repeater Power Amp I ran a Mirage C2512G (s/n 30820) for a number of years at a reduced Pout (around 75 watts out of duplexer) and had no problems. The amp case is mounted on a very large heat sink for repeater use. Its only glitch was a nearby lightening strike that vaporized the output cap of the PA. Replaced the cap but never put it back on line as most users never noticed it wasn't there.

I have one of the OLDER Mirage amps, I think it has been around here for 12 or more years at least, perhaps more. This SHOULD be pre-MFJ. My model is 25 in for 120 out. I planned to run 10 watts or so in for 75 or so out. Is this a reasonable choice? - Mike From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Michael Ryan Sent: Friday, March 13, 2009 11:51 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] 220 Repeater Power Amp Does anyone have some advice about what to use for a power amp in a 220 repeater? MIRAGE makes a 90 watt model they claim is for repeater service. I don’t see anything else around. I’d be happy with 60 – 90 watts MAX output with maybe 10-20 watts drive. – Thanks.. - Mike __________ NOD32 3935 (20090313) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com <http://www.eset.com/> __________ NOD32 3935 (20090313) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com <http://www.eset.com/> __________ NOD32 3936 (20090313) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com
