Problems at Radio Station W4OTN

Thu 22 November 2007

I've been having problems with my radio station lately and it has really started to bother me. I've used two antennas and haven't been satisfied with either one of them. Before I was using a 40-80-160 dipole but the 80m portion was too long and didn't want to work right …

Last night I put the final touches on the 20m vertical antenna I built the previous night. Looking over everything and checking it twice I thought I had everything taken care of. I looped a branch in a nearby tree and pulled the antenna skyward so that the base was …

I'm going to build a new antenna I found in the 2003 edition of the ARRL Handbook. This antenna was originally published by the ARRL in their September 1984 edition of QST in which Chuck Hutchinson, K8CH, explains his "Tree-Mounted HF Groundplane Antenna".
