7 BAND HF COBWEB ANTENNA 1kw 14,18,21,24,28,50,70 MHz socket SO239
Multiband cobweb antenna works on 7 HF bands and up to 1000w. Bands are 14,18,21,24,28,50,70 MHz. Built and modified by me for my friends and other radio hams. This antenna has sides of the square 2.65 x 2.65 m, and is very useful where space is limited. This antenna works well as an antenna for your base but equally well as portable for holidays and field work due to it's folding boom arms. It's unique design allows this antenna to be quickly and easily set up within a few minutes. It's design is very strong and robust, and is resistant to strong winds. The antenna is contructed from glass fibre rods, aluminum, stainless steel and galvanized steel and has a sealed connector box resistant to rain and UV rays to keep the balun and connections from the elements. The antenna has an impedance of 50 ohm. The antenna works well on DX and as a QRP station. It is pre-tuned to different bands at a height of 4 metres above the ground. Raising the antenna above 4m will generally see SWR decrease. Bandwidth on 6 and 10m may require the use of an ATU to cover more of the band. This antenna is omni-directionally so you do not need a rotator. It is made up of folded half-wave dipoles for 14,18,21,24,28,50,70 MHz.
Polarisation is horizontal and is naturally resistant to some electrical interference and static. Large system efficiency to 95%. Socket -- UC1 / SO239.
Max power supplied 1000 Watt. Antenna gain on all bands 5 dBd (7.15 dBi). Minimum SWR 1.1: 1. Can accommodate any mast up to 52mm in diameter.
