Dual band feed antenna 2.4Ghz & 10Ghz for QO100
Dual band feed antenna 2.4Ghz & 10Ghz for QO100 (POTY)
The POTY / Patch of the Year is a 2.4/10.5Ghz dual-band patch antenna, circular polarized 2400 MHz TX and linear horn antenna 10500 MHz RX with dielectric lens, for the QO-100 satellite / Es'hail2.
It is a kit antenna to assemble.
Amateur radio design: G0MJW, PA3FYM and M0EYT
Amateur radio manufacturing: PE1CKK
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 sise depend on avalable TX power.
It is normally cheaper to get a bigger Dish than expensive Power Amp for TX and you aloso ge the benifit of a better reception signal as well.
Recommended Dish 1.2Ghz
