[amsat-bb] amsat-bb] dual dish feed for Oscar100?

[Edward R Cole]

Gabriel,

I do not know if available in EU, but I used an 86cm offset feed dish 
originally used for Ku-band satellite TV here in the US for receiving 
AO-40 2.4 GHz telemetry.  It used a six turn helical feed and db6nt 
preamp to Drake downconverter to 123 MHz IF (FT-847).

I use a 60cm offset feed dish, commonly used in the lower-48 states 
of the US for satellite TV for my 10-GHz station.  Feed is W1GHZ 
linear pol feed with corrugated horn.  Most likely you will need a CP 
feed for Oscar-100.

Many eme'rs are having success on  10-GHz with as small at 60cm 
though 1m is better (for eme).  I suspect Oscar-100 signals are much 
stronger than eme.

I am not QRV on satellite at present but have plans to restore my 
AO-40 antenna system this summer using a FT-736R on mode-UV or LU sats.

I am looking for a dual band dish feed for 10GHz/2.4GHZ to use for the Oscar
100 downlink/uplink.

What is your recommendation of either a commercial or a simple to build one?
