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 and labor, the radial assembly is shipped flat but fully soldered.
- radials must be bent
- connector, nut, and "rubber ducky" must be screwed together
- heat applied to shrink tubing
This is sold as a kit in order to pass savings on to you (reduced labor and shipping).
Specifications:
- Manufacturer: Lothar of The Hill
- approximate 1090 MHz center
- 1/4 wave design
- uses inexpensive F-type connectors and RG-6 cabling
- impedance mismatch (50/75-ohm) loss @ 0.14 dB
- nominal 2.5 dBi gain
- water resistant (potentially waterproof, but not certified)
