My QSL confirm rate is 100% - Cards will be replied as they are received! if you QSL direct, i will QSL direct, same with Bureau and eQsl. i strongly prefer real paper QSL cards for my collection Operator handle is Chris, i was created in 1970. current gear includes (but is not limited to ;-). RX/TX: Yaesu FT-450D with LDG ZII PROII and homebrew digital PWR/SWR meter. Ant 1: Homebrew 6-band Hexbeam, 2 elements on 6-10-12-15-17-20 meters (40 with ATU) Ant 2: Homebrew 5-band Cobweb, 1 element on 10-12-15-17-20 Ant 3: 10m HF Gainmaster vertical. Ant 4: 20m homebrew VDA (Vertical Dipole Array) very efficient end-fed half wave with reflector. Ant 5: 5-band resonant vertical, 23 meters long, on fibreglass pole, for all bands when portable. (if your QTH is space restricted i can really recommend the multiband Hexbeam design!) for more info on my antenna projects & alot of DIY , check my site, HERE QTH located in Denmark, in the Northern part of the Sjaelland archipelago (IOTA EU-029) about 45Km north of the capitol Copenhagen. Radio has been a part of my entire life, both personal and proff. i work as an electronics engineer and have been SWL listning since childhood. I also enjoy being portable on the HF bands, using my homebrew arsenal of antennas. Newest addition to my antenna farm, a 6 band broadband Hexbeam project. April 30th , 2013: i've already worked West Malaysia, Guadaloupe, Maldive Isl., South Africa, Hawaii with great results. This antenna really rocks. Despite it's size it has aprox. same data as a 2 element full size yagi. not bad for a bunch of wires and fibreglass. Cobweb 5-band design gone mobile. Cobweb down for inspection. VDA - Vertical Dipole Array, as used by many DXpeditions, end fed halfwave for 20 meters. the red element is the driven element, the blue one is a parasitic reflector. This design gives aprox. 3.5db forward gain and very high feed impedance, no elaborate ground system needed. the antenna design can be optimized for max forward gain or front/back attenuation. This is why the VDA is so popular with DXpeditions. (this was modelled from my own antenna)
Gas prices being what they are, i got myself a smaller car (a lot smaller hi hi) and had to come up with another form of mount for portable operations. i also put the cobwebb on the shelf and set out on a quest for the "perfect portable multiband antenna". Some quest that has been, but i learned alot along the way. anyways, here is the current portable setup with a halfwave loaded vertical for 80 - 40 - 20 - 15 - 10 meters. it's working a treat, but only on 5 bands so far. you may have guessed i prefer high impedance antennas, because i hate laying out radials when portable.
49:1 Impedance transformer used to match the TX 50 ohm output to the ~2700 ohm
feedpoint resistance of the vertical above.
the antenna wire itself, with 40m coil assembly in plastic container to keep the rain and snow out.
The coil is wound on 32mm pvc form and sealed with heat shrink tubing.
