I refer to mine from now on as a “CobWeb” Coaxial Collinear Antenna-- 432 MHz -- From Via N9ZIA Small 70cm. MFJ-1836 and MFJ-1836H. MFJ has created a set of 1/2-wave dipole antennas folded into a square (sort of a cobweb antenna). There are two units that cover 10m-20m. They are the MFJ-1836 ($229.95) that handles power up to 300 W, and the MFJ-1836H ($259.95) that handles up to 1.5 kW. These antennas are roughly 12-feet as measured diagonally across. 20m, 17m, 15m, 12m, 10m operation. Compact and easy to handle – Under 8ft square. Doesn’t have to be too high – Reasonable performance at 10ft, with 20ft being the ideal. Can be made with either figure-of-8 speaker wire (folded-dipole) or single-wires and 1:4 balun (for impedance matching) Can be constructed with PVC tube or fibreglass poles. New white tower strobes and runway strobes are all LED now (a friend designs them for Siemens) Take three foot jumper cable and cut all but about an inch or two to splice to the top element 05-30 MHz: NTi: MD300DX Wideband Active Antenna 9 kHz - 300 MHz: Vibroplex-Par: EF-SWL End-Fed Dipole Antenna 1-30 MHz: Princeton: SkyWave End Fed Random.

Sky-gray fiberglass spreaders and nearly invisible wire elements (flat 9x9x1/2 feet square, 8 pounds) blend in with. The antenna is about 60 feet away from any houses so I guess the combination of that plus its supposed lower immunity to noise is working but early days yet. With an ATU it will load up on 60M, 40M and 30M and I can hear quite a few stations but it is early days yet to really assess what the efficiency is at these bands. These antennas are good and efficient antennas often used by radio amateurs as well as for various commercial and military applications. Some of these miscellaneous antennas are Cardioid pattern antennas, Four Square, Lazy-H, W8JK, ZL special, Moxon, Cobweb, Hex-beam, Bruce array, Bobtail curtain, etc to name a few.
