I'm working with portable setups, even from my back yard\nlike I showed in the videos I posted earlier today, and do well without\npreamps. I use short RG58 coax runs - 10 feet (3m) from antenna to\nradio or diplexer, and 3 feet (1m) from diplexer to radios if I am\nworking SSB/CW. Modifying K4FEG's statement to \"YOU *MAY*\nNEED A PREAMP\" would be more accurate.\n\n73!\n\n\n\n\n\nPatrick WD9EWK/VA7EWK\nhttp://www.wd9ewk.net/\n", "attachments": [] }
