10M band RFD Resonant Feedline Dipole Report


Well, it works!

A few weeks ago I made up a resonant feedline dipole for 10M as an experiment and the initial measurements looked good,. (Post http://acomeau.blogspot.com/2011/10/10m-band-rfd-resonant-feedline-dipole.html ) This weekend I used the ARRL sweepstakes contest as a way to get a few quick test QSOs in.

I threw the end of the antenna up in a maple tree in the back yard, connected up a spare feedline into the house and tuned the antenna up.

The bottom of the 10M band looks good, with SWR <1.5:1. The upper end of the band is just as well.

I ran a few QSOs in the contest, as well as a few DX QSOs into Europe. The listing below are the local and DX contacts. 6000km is not too bad for a few meters of RG-174 and automotive wire. I was running the FT2000D (100W+ PEP SSB or 20W PSK)

A dash of calling CQ on PSK tells me, by looking at PSK reporter, that the my coverage easly includes North America and Europe. There was a Brazillian station I could copy but he was not able to return my reply.

Humm, so I guess all that is left is to forge ahead with the full 80m version hung from a kite skyhook!
