Not much luck this week with radio, but I do have some interesting things coming. Included is some footage of my recent attempts.

This is an off-center-fed dipole By Spiderbeam, the famous antenna mast manufacturer. It does work on the advertised bands, though your SWR will vary depending on location. I would prefer connectors instead of the wires straight into the potted BALUN... It is fairly light and the BALUN works; I only tested it to 50W on 6m. There will always be some residual common-mode RF current on the coax shield though, as with any OCFD antenna. The antenna radiator is made from UL-wire / Liv-2Yz (ultra light aramid synthetic fibre and copper strands, Insulated). The antenna comes including 12m coax which despite the low weight (only 185g) shows only very modest losses (~1dB on 40m, less than 2dB on 10m). Despite the lack of connectors which would make repairs very difficult, with careful handling, the occasional QRP tuner and maybe an extra RF choke, it looks like a decent choice for multi-band operations. I need to test it on other bands and in a different environment...

Copper tape can be used not only as shielding but as an antenna element. I bought mine on Ebay. Garden supply stores or hardware stores might carry it. You can imagine many uses on windows and other surfaces.
