Portable mode V/S antenna set up

A portable mode V/S antenna set up. The 145 MHz part of the famous Arrow was used, with a custom made mounting for the S-band downconverter from Kuhne. A bias-T was used to power the downconverter. The patch was soldered for RHCP (the original instructions were for LHCP). The semi-water-proof was made of an empty salad box (the cucumber version works fine :-)).

The set up was succesfully used on AO-51 mode V/S. Several contacts were made with two FT817NDs, and a Heil headset. All powered from a single 2.2 Ah battery.

Thanks to John G7HIA for providing the patch antenna, David G0MRF for providing the 2.4 GHz source for testing, and AMSAT-UK in general for selling these items (and doing all other good things).
