Boris the Spider ADS-B Antenna Kit

Boris was designed as a low cost entry level antenna for 1090 MHz ADS-B reception. This DIY kit is a simple and cost effective way to get started receiving ADS-B.It is a quarter wave ground plane design with a nominal 2.5 dBi gain. It was designed to out perform the cheap printed circuit board antennas while being a similar cost. It was also designed to be less expensive than other home made "spiders" using panel mount N or UHF connectors and to be water proof. The most important feature is that Boris uses inexpensive satellite rated F connectors and cabling. The 50 / 75 Ohm mismatch loss is only 0.14 dB. Use of RG-6 and F connectors means that antenna cost and installation costs are significantly lower than other home brew antenna designs.   Items Included: a 1090 MHz "rubber ducky" a satellite rated F-81L connector with a panel nut a radial assembly (pre-soldered, but you need to bend) a short piece of heat shrink tube an F Female to Male SMA connector To save on shipping a
