RTV on ku is weak, and it's SD not HD (S2). How much loss does the feedhorn cap contribute ? I'll pop it off and see. I've seen some commercial installations that leave them off despite the bug warnings.

Thanks for chiming in here. No limbs or obstructions here for that satellite. No I don't have another HD box to try. I was really keen about the new Traxis but everybody (dealers) are telling me to stay away...hmm. No the 'bouncing signal' is a Geosat DVB-S2 issue, the standard DVB signals say on 137 W (Alaska nets) are all solid ! So disappointed with this HD stuff, especially since it's totally unnecessary (480interlaced) for classic tv shows.

Maybe they can calculate a 1db loss in a perfect world, with a 20 foot dish where there's so much gain to start with or something, but it's false advertising to say there's only a 1db loss in every situation. Even so, 1 db equals a 26% signal loss in a perfect world.
If you still insist on trying for circular signals, Google "c band waveguide polarizer".

I only went for this international feedhorn because it was on special and was practically new, if I knew it was going to cause such a significant loss and all the added grief I would plonked down the extra dineros and bought a regular Corotor II Plus.
Thanks Primestar for your sensible comments here.
