How to use dual band feed?
How to use dual band feed?
Hi Folks
I'm very new to Amateur Satellite, so I'm sorry that my question may seem very basic.
I've purchased an Octagon Green PLL LNB, and am currently awaiting for my 1m dish to arrive. Eventually, i'd also like to transmit, but I have no idea how to use the "copper pipe" type dual-band feeds, like this:

Where does the LNB go? And which way round does the feed go?
Thanks

Mike,
All the talk is about dual patch
I am hoping to use a separate 1.2 M dish for Datv transmission via qo 100
Is there a single band patch antenna
Maybe the one on page 40 of cq TV 263 ?
Could you confirm that a lhcp patch reflects at the dish to become rhcp

G3RUH does an excellent 2.4 GHz patch.

Re: How to use dual band feed?
to be absolutely clear: the AMSAT-DL dualband feed is not (NOT!) compatible with PLL LNBs as it has an SMA coaxial connector for 10 GHz. It can therefore receive ONLY one polarisation and it needs special LNA/downconverter setups, not an LNB.
