I tested the difference before changing my feed line\nwith heliax ldf4, and you can hear a difference on low elevevation\npass. I really think it worth it, even if you have only 50 feet run. I\nhave alsmost the same lenght of feed line at my place.\n\n73\n\nJ-F VA2SS\n\n2009/12/18 Elan Portnoy <[email protected]>:\n> Hello all,\n>\n> In the midst of all the excitement around the new birds, I have a question for all of you:\n>\n> I have ARR preamps on both the 432 and 145 transmission lines. At the moment, they are located in shack, just before the transceiver.\n>\n> Both lines to antennas are 50 feet (15.24 meters) of LMR400. How much of a performance improvement should I expect from mast mounting the preamps? It could be done, but I'd rather keep them inside if there's nothing to be gained.\n>\n> Thanks,\n> Elan - WB2IOL\n> _______________________________________________\n> Sent via [email protected].
