@hamchallenge Apparently this was also an ahead-of-schedule #HamChallenge #HC33S I built a six-band linked dipole with links for 10m, 12m, 15m, 17m, 20m, 30m, and 40m meant for inverted-V deployment, to be an efficient, mostly isotropic radiator with high Q on one band (at a time). I want to be able to POTA with friends, but we tend to desense each other, so I'm trying for more band isolation as one tool in the toolkit.My toolkit for isolating now includes:Roofing filters in the KX3 (but not in the IC-7300, sadly)A 100' coax extension to move at least one antenna to keep them out of each others' near fieldsExternal QRP bandpass filters for the KX3 (but haven't built 100W capable bandpass filters for the IC-7300 yet)Polarization separation via loaded JPC-12 and JPC-7 antennas (with relatively low Q)Higher Q in this linked dipoleA dual-tapped QRP 9:1/49:1 unun to let me move either an EFHW or EFRW away from my KX3A 49:1 unun to let me move an EFHW away from my IC-7300Because I expect to operate QRP mostly on CW, I tuned the links for the low ends of the bands. I started by tuning 10m, then added one set of slightly-too-long links at a time, hoisting it on a mast to measure with a NanoVNA, and trimmed the ends evenly to move resonance up only as far as I wanted.I used 2mm bullet/banana connectors to connect the links, and lightweight static line for the links, so that they would be flexible and be able to wrap up on a winder.I chose the size of the winder to be able to hold a 40m dipole with thin wire, and to be able to hold FT82, FT140, or FT240 toroids for common-mode so that it can be realized for any desired power level from QRP, to barefoot 100W, and beyond.I chose RG316 for the balun/choke because of its PTFE dielectric that can take a tight radius bend, and used that for the entire feed from the radio.I designed the winder to be small. My next linked dipole will use Vectran-core DX-WIRE UL, and I'll modify the design slightly.
