An easy to build antenna for seaside locations 17m and 15m versions were used at 9M0O DX-pedition in 2016
• Wire lengths R and D are from the boom center line.
• My suggestion is that wire ends are not bent around an egg or so. The dimensions are not valid in such a case.
• Good choice for the driven element center isolator is a commercial isolator with UHF-connector. The coax center conductor is connected to the upwards going wire.
• Current balun is at least 3 pcs Amidon FB-43-1020 or similar on the coax cable next to the feed point.
• Cable route to the feed point is from the back of reflector, along the boom. Cable influence is then minimal. • An easy way to fine tune SWR is to adjust distance between element lower ends
. • Bringing them closer to each other resonant frequency goes downwards, and the opposite
• Cable ties are good for temporary installations. They fix everything in this antenna. • Spiderbeam telescoping masts are good for this antenna. Fishing rod is good for the boom.
• Salt water makes angle of radiation low. Also losses in ground reflection are low and antenna gain therefore close to 10dBi. See More in .pdf file :
