The real issue is the quality of shielding, and the placement of\nthe leads. You will be operating in the near field of the antennas, and you\nwant to minimize RX pickup from the TX antennas before you get to the\npreamps. RG-213 is a single shield coax, while RG-214, Bury-Flex, and\nRG-9913F have double shielding. While the double shielding is better,\nespecially if the cables run close and parallel to each other, many people\ndo fine with RG-213. Note that the generic versions may have significantly\npoorer shielding. \n\nThe UEK-3000 has 30db gain, and an 80' run with the 2 meter IF output should\nnot be a problem. Back in Ye Olde AO-40 Days, I had a 70' run of RG-8 down\nto the shack. It was there, I was in a hurry, and it worked. (If you have\none with the 70 cm IF, the answer is less certain.) Be aware that RG-6 is\n75 ohm rather than 50 ohm cable, the big brother of RG-59, so the SWR on the\nline will be a bit higher. However, that should not be a problem.\n\nGlad to hear someone else is keeping the faith on HEO.\n\nAlan\nWA4SCA\n\n \n\n\n", "attachments": [] }
