Finally weather dry enough and not too cold to work outside so I got up on the roof for a closer look at the pesky wire antenna with unacceptably high SWR. I noticed that condition when my Kenwood HF refused to tune up on 80m altho it was tuning on 40m. So I loosened the center halyard to drop the balun within reach and immediately spotted the problem. The electrical connection on the shorter leg of the OCF Dipole had snapped off (see picture) so no wonder I had lousy SWR. My junk box contained the proper lug connector and easily crimped it in place and rehoisted the dipole. New SWR’s are as low as 1.1 on 17m up to 2.6 on 15m and 3.5 on 30m. The biggest improvement was on 80m; it is now 1.9. The Kenwood TS-590 does manage to tune up on 30m. Next project: test that the old Yeasu FT-900 works well enough to sell it with a clear conscience.
With a tip of the hat to the Drifters and Carole King, here’s what I found up on my roof yesterday. So, what do you call half a dipole? Answer: a lousy antenna!
