Hi Alex.
I have about 20 deep parabolic prime focus aluminium reflectors in the shed of 90cm diameter, complete with a single arm feedhorn system. They are not really much use at Ku frequencies owing to the feed already fitted on them (matched to 10/11 GHz), but they would be ideal for mounting of a dipole for research lower down in the microwave band.
I did some tests a long time (fifteen years ?) ago with them for audio phase shift measurement using two installed some 10 metres apart with microphone/speaker focal adjustments, and submitted a paper to someone in France to dispel their notion that there was only one focal point which could be used for sonar locating.
Problem is they would most likely be damaged if delivered to Scotland, but if you are in the area, you can have them for some food coupons. You will have to build a supporting for any clamping arrangement. |
