I am not a member of QSL bureau, but I log my contacts in eQSL and LoTW.

If you need my printed QSL, just send me your card direct by snail-mail. No SAE/SASE required, no IRC or money - only your QSL, and I will send my card in response, also direct at my expense.

My homebrew four-band (20-17-15-12 m) very lightweight 2-element "Jungle Job" type beam (G4ZU) at 12 m above the ground. Multiband matching is achieved by using a carefully calculated T-match at the feedpoint with a variable capacitor rotated by a small remotely controlled servo motor. The whole mast is rotated by Yaesu G-1000DXA rotor from bottom.

For seven months in service, only on weekends with barefoot 100 Watts, 251 DXCC countries were worked using this simple antenna. DXCC was confirmed on each of its four working bands. Now this antenna is disassembled and replaced with 4 ele OWA Yagi for 10 meters, see below. 

 

I never paid attention to 10 meters band, so now it is the main showstopper to my 5 band DXCC award (apart from missing 15 countries on 80m). In April 2015 I've modelled and built 4 element OWA Yagi for 10 meters band, on a 4 meter boom, using only 2 meters long aluminium alloy tubings (mostly square) available in the DIY store. Well, it worked as calculated from scratch, providing SWR < 1.1 in the 28.0-28.75 MHz range, with the same gain (modelling shows 8.3 dBi in the free space) and F/B ratio (> 20 dB modelled, but actually more in reality on distant paths) across all of this part of the band. This is what I expected from OWA design, and what I've obtained without difficulties. It took just one weekend to build and install this antenna.

If you contact me on 10 meters, please upload the confirmation to LoTW: maybe I need your country for my DXCC record. Thanks in advance!
