LNB assembly on the POTY antenna

The quickest and easiest way to mount the POTY antenna on the LNB is to drill a 22mm hole in the plastic cap in front of the LNB and push the POTY waveguide inside.

Push the POTY until it meets the metal horn inside the LNB. By rotating the POTY, you get the flex out of the cap and the waveguide stays in position.

With silicone sealant, the LNB head will be fixed and waterproof. The mounting on the support of the dish is to be done just before the reflector patch, on the tube of the POTY and not on the LNB.

Recommended Dish size depend on available TX power.

It is normally cheaper to get a bigger Dish than expensive Power Amp for TX and you also get the benifit of a better reception signal as well.

Recommended Dish 1.2Ghz
