This was introduced a couple of months ago. I didn't see anything in this forum, so I though it would be worthwhile to mention this. It solves the problem of mis-calbration between the rotor and the control box.;
, I do see three problems/issues;
1. There is a 2db additional loss
. This is because the downlead goes through
the rotor and
the control box as opposed to straight from the antenna to your TV.
2. This is fine for one TV, but for multiple sets, the feed for additional outlets would have to be off the output of the control box
, not up near where the downlead enters the building (attic or crawl space). This is a serious issue with any setup other than one or maybe two TVs', especially where one has a 'weak signal' issue(s).
3. If you need to 'amp' the signal and you have issues with very strong and
very weak signals, the amp would be after the control box also where additional loss already occured.
DiSEqC sounds good on paper, but with the small 350ma current limitation, it restricts the size of the motor and puts a serious restraint on the touque of the rotor. Fine for smaller antennas, but a possible problem for very large installs, just as with FTA dishes. Running a 2nd wire along with the coxial cable is really no big deal. Cost and labor time is almost nill.
