one > keep the feed line perpendicular to the feed point for such a distance/ You don't need to keep it perpendicular for that length. Some people just use a post X feet (5-6' is a SWAG) from the vertical as a support, and then run the rest on or below ground to the shack. > 2 Do most users switch to RG 8U for longer runs? Using better coax is always a worth-while investment! On 10m, you will easily save about 1 to 1.5 dB per 100' by changing from RG58 or RG8-X to RG8U. If your run approaches 200', going to something like LMR-400 is very worth it, as you save even more dB's on the higher frequencies. > 3 Does using an ant tuner at the rig offer any benefit with the Sigma? For the most part, no. If you operate within the 2:1 VSWR curve, the loss due to mismatch is negligible. > 4 What methods are being employed to keep the ant out of reach of persons > who might pass by? Trained attack squirrels. Kenny K2KW -------------------------------------------- Force12Talk mailing list provided as a service by Force 12 Antennas, Inc.
