wasted all day on 121w,the receiver would do a blindscan and pick up 1 tp at a time but not consistently.
I did detect 3 tp's but not enough to assist in aiming.
Finally swung around to 91w,I had the pole marked for 91w ku already.Elevation is 4 degrees higher than ku,this I remembered from 10 years ago when I did an experiment just strapping an lnb on to the existing 3 armed primestar 1 meter dish.
conical scalar isn't critical,it all depends on if the lnb is pushed all the way forward or all the way backwards.
I did try it on the very edge of the lnb and again pushed in so the outer part of the lnb formed the final ring.
I didn't see any performance difference.I am actually using a flat scalar from the 1980's on it now.
For a novice I would aim a dish ku for 91w and go for that one 1st with a c band lnb.
The one I am using now is a kludge with the ku portion ripped off and replaced by copper foil.My holier than thou lnb.
for aiming 3820v 30000
quality is 70% which is better than some of the ku sats i get.
Clear sunny day out.
Lnb arm is ripped off a 80cm dish and mounted on the wrong side of the dish but still works good.The original was a 3 armed 1 meter primestar retailer dish.
