3-band feed 2.4 / 5.6 / 10 GHz for setting up an antenna or antenna system
with a offset dish
e.g. for operation with ICOM IC-905 or corresponding home-made stations

Development by DJ7GP & DH9RA

usable frequency ranges:

1.) 2,300 – 2,450 MHz
2.) 5,650 – 5,850 MHz
3.) 10,000 – 10,500 MHz

> linear polarization
> antenna impedance 50 ohms
> SMA connection sockets
> load capacity: 100 W
> The decoupling between 2.4 GHz and 5.6 GHz is approx. 20 dB.
> The decoupling between 2.4 GHz or 5.6 GHz and 10 GHz is greater than 80 dB.
> SWR at the band limits < 1:2.0
> material aluminum
> including optimized concentrator
> all screw connections made of stainless steel
> shaft diameter Ø 23 mm
> weight: 120 g
> we recommend a weatherproof housing for operation
