Joe, Re the LMR-400 coax: No, due to dissimilar-metal issues. Use RG-142B/U or RG-400/U for in-cabinet wiring.
Re the Daiwa: No, due to potential IMD and losses in the UHF (gasp!) connectors. Re the Diamond antenna: No, due to quality difference between it and a commercial-grade antenna. Consider a DB antenna. Re the Kenwood TKR-850 repeater: I consider the TKR-850 to be roughly equivalent to a Motorola GR-1225, meaning that they work very well as low-tier repeaters for non-demanding applications. If you want a current model repeater that is roughly equivalent to a MICOR, consider the Motorola MTR-2000 or a Kenwood TKR-840. The latter requires a separate PA. Before we leave the topic, would you please explain the problems you had with your MICORs? There are many pro-MICOR folks on this reflector who would like to know exactly what problems you have or had with those repeaters. Perhaps others can help you resolve those issues. Please give us that opportunity. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of kc7ght Sent: Friday, March 16, 2007 1:13 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Coax for cabinet and for feedline - other than hardline Gentlemen, Is LMR-400 a good coax to use for my 70cm repeater feedline. My feedline is 130 feet long and located at my house. Should I really go to hardline and replace my LMR-400 feedline? If so what diameter? Will it really be worth the cost and trouble to run it through my attic and into my house? Your article indicates that some LMR-nnn coax are OK for cabinet connections. Is LMR-400 Ultraflex a good choice for cabinet connections? I am using RG-142B/U now for my duplexer connections (an Angle Linear custom made duplexer, bandpass cavities, and preamp). Should I use RG-142/B/U for my (30 inch long) Tx to duplexer run also? I would like to keep my new Daiwa CN-801 (UHF connectors) SWR Power meter in the Tx line permanently. Is this a good idea? It is comforting to see the power and SWR at a glance. I am using a Diamond X510MA (17 feet long with a UHF connector) dual band antenna at 65 feet high. Should I be using a different antenna for my repeat operation? If so, what antenna? Is the Kenwood TKR-850 repeater a good unit. I just ordered one to replace my Micors. I have nursed my two Micors for the last year, and just gave up on them. One problem after another on both units. Please let me know your thoughts and suggestions Thank you. Joe KC7GHT
