This is correct.saguaro said:My understanding is that linear LNB for FSS satellite should work with either reverse polarity dish (such as Toroidal) or a normal dish (such as Superdish).
Reverse polarity dish (such as Toroidal) requires reverse polarity LNB only for circular polarity DBS satellite.
If I am wrong, someone please correct me.
Smith said:Reversing polarity for linear sat signal means 90 degree, not 180.
For circular LNBF, rotation to any angle DOESN'T matter - need changing internal circuit, ie reversing 13/18 VDC or DiSEqC control signals.
Hell, I'd love it if someone could just reverse any DishPro lnb.HDTVFanAtic said:You are any of the good engineering people on this forum know how to reverse an Invacom Quad 0.3 so you could get a reversed circular 0.3.

What I wouldnt give for several of those - and it sounds like I might not be the only one.

delanewf said:I've been reading this thread and I can't find out the answer to my one question: Will I be able to get all the HD channels with ONE dish? I live in Pennsylvania, and my only solution right now is 2 dishes. That is not happening while I am still married. I was lucky to get one dish on my roof. I won't upgrade to any new HD channels or the new 211 receiver until I know I can get a One-Dish solution.
I hope that is what E* is planning. I am hoping that I can replace my Dish 500 with a 500+. If they move all national HD to 118.7, the Dish 500+ should be my ticket to the One-Dish solution, right?
Will we find out soon if this is what E* plans?
Smith said:Invacom LNBF would be easy to mod comparing to Dish DP LNBF;
there are two ways to do it - try to contact Invacom _sales_ department and convince them make 1000 LNBF at least ( remember it should be profitable for the company ) or give the LNBF to one of us for dissecting .
Derwin0 said:That will not work for circular signals.
I mount an entire dish upside down to get a low angle (148), and it still works. So being upside down changes nothing for a circular signal.
Normally a Dish 500 can only go down as low as 14 degrees before hitting the bracket mount. By Mounting it upside down, I can get it down as far as 4 degrees, which is good since my EL for 148 is 6 degrees.HDTVFanAtic said:At the risk of asking a foolish question, hell that's never stopped me before , why would one mount a dish upside down and what are the advantages?
I tried that at first, but the wall face that I mounted the mast on didn't face the right direction. So I decided that an upside down dish on a plumb mast was easier to aim than a tilted mast.JohnH said:I just tilted the mast on the 30" dish to get 148. Looks better with it pointing at the ground.
Need a different LNBF.oljim said:Would a 105 SD work for 118 if 105 LNB was pointed at 118?
