I have an Invacom LNB which is now getting on, but its a great bit of kit. The problem is that I've noticed that the window which protects the feedhorn has a a big hole in it; probably due to ageing, the unit still works fine. Can this be replaced? It looks like the actual housing is moulded plastic, can this be removed? I have an old faultly LNB and was thinking of pitched the cap and somehow fitting it to this unit.
 
Hi Smiffie ..
So long as the material chosen to cover the feed is transparent to the incoming signal it should be ok ..
A cover grafted from another LNB should do the job just fine...

Might be worth checking for signs of any water ingress, if so then a replacement required.
 
In the end it was a pretty straight forward job, the weather proof cover simply clipped off and the I used a craft knife to cut the remaining bits of the plastic window off the feed horn flange.
The only damage I could see was where peices of the window had flaked off and dropped down the horn, which I shook out.
I then marked up a thin sheet of plastic using the flange as a template, cut a disk out of the sheet and glued it onto the flange using araldite rapid. Re-clipped the weather proof case over the top and re assembed, ready for the winter.
