I have not taken a new plot with my Rig Experts AA-30 since I changed the antenna from more of a traditional Inverted L to this “inverted fish hook” configuration, so I decided to set the range from 1700 – 15000 khz and see if its any different than the old configuration:
This the OLD plot – when the antenna was a standard Inverted L, and here is the new plot – this time just covering 160 – 20M:
There is a little difference, but not enough to make the antenna appear much different to the Palstar AT2K tuner in the shack – or to the 1:1 current choke at the base of the antenna.
I’m also going to send the plot to Bob at Balun Designs to see if maybe an UNUN might be a better choice than the 1:1 current choke. I doubt it will, but I thought I’d ask – since this is Bob’s expertise.
80M is the only problem band – and I’m thinking maybe I could use the 1:1 current choke on 160, 30 and other bands, but switch in a 1:2 UNUN for 80M.
I’ll update this post after Bob gets back to me. I highly recommend Balun Designs products – Bob is the nicest guy and builds superb quality products at a fair price.
