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) 2-element "Jungle Job" (G4ZU) type beam at 12 m above the ground. Made of aluminium alloy (driven element, T-match and and the boom), copper wire (four reflectors) and synthetic fibre ropes. Multiband matching is achieved by using a carefully calculated T-match at the feedpoint with variable capacitor rotated by a small RC servo motor. The servo is remotely controlled by RC servo tester at my desk.Very lightweight (about 6 kg) but robust antenna. The whole mast is rotated by Yaesu G-1000DXA drive from bottom.
The antenna and mast assembly can be laid down on the ground unlike the SpiderBeam/HexBeam type antennas that require telescopic mast and several friends to assist with guy ropes. I can easily put the whole system up and down without any assistance. The price for this is that my antenna has no director elements, but I consider the difference of 1 dB in gain is negligible. Moreover, the longer driven element fully compensates this loss on 15 and 12 meter bands. With Jungle Job design F/B ratio is the same as in 3 element beam, only the main lobe is wider.
