To Robert's question about a balun or un-un at the feedpoint, I have recently installed a Balun Designs unit on my OCF. The quality of the workmanship is very impressive; I really recommend their work. A good choking device at the feed (exactly what kind is determined by your antenna style) can go a long way.
Also -- good quality coax, with a high percentage of braid coverage is a must. With good connectors properly soldered completely. Even for your short jumpers (tuner to rig, etc). At the shack end, an effective SINGLE POINT ground is important, too. No daisy-chained grounds. As others have mentioned, shielded cables in the shack (like the Granite firewire) help a lot. RF is sneaky. Coil up unused speaker leads (or cut and re-terminate). Ferrite beads are cheap bonuses. You can even add them to the coax at the shack end. Experimenting will lead to happiness...eventually. 73, George J Molnar Las Vegas, USA Amateur Radio: KF2T Twitter: @GJMolnar _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
