Hi there, location is Pontefract west yorks. I am 150 asl and have a 30 foot mast for radio ham work - i`ve mounted the little curlywhirly supplied at 30 feet with 66 feet of good quality satellite cable - Ok, it`s at 75 Ohms but it`s for receive only. As others have rightly mentioned, height is the thing and i think a few more yards of decent coax won`t do much harm. Been running the new 3.07 version for a week and have kept the polar diagram for that time - see attachement. Regards and good luck, Roger PS No preamp used - too close to transmitting antennas.
