that's pretty much par for the course. i haven't come across anything to stop that. my hd does the same thing and i have high 90's and 100's cross the board.
Move somewhere that it doesn't rain as hard.ub1934 said:We had some heavy rain come through here in the North East and we (as we always do ) lost 99c/s & 103c/s , 101 , 110 , 119 all will drop to the low 60s to 70s & no loss of picture , without the rain 99 c/s & 103 c/s all read low to mid 90s with some 100s so what else can i check to stop this , Thanks![]()

I had the dark red stuff in Northern Va, was the bottom of the storm you had I think. I only lost for a second around 845, then all was well.ub1934 said:We had some heavy rain come through here in the North East and we (as we always do ) lost 99c/s & 103c/s , 101 , 110 , 119 all will drop to the low 60s to 70s & no loss of picture , without the rain 99 c/s & 103 c/s all read low to mid 90s with some 100s so what else can i check to stop this , Thanks![]()
True, doubling the size of the reflector will increase the antenna's gain (and therefore G/T) by 6 dB, but it only works to a point. If you increase the receive dish size too much you reach the point of diminishing returns. A bigger dish also receives more thermal noise. I discovered this a long time ago playing around with link budgets. I kept increasing the size of a Ku-band receive antenna expecting the receive C/N to get greater and greater. It did to a point, but after that point there was no further increase no matter how large you made the dish.eakes said:The only way to increase the fade margin would be to increase the size of the antenna. Consider that the present dish is 3 ft diameter (about), a 6 ft antenna will increase the gain by 6 db, a 12 foot diameter antenna would increase the gain by 12 db.
Yes, there are a lot more factors to consider in path design than my very simplistic example. I was just trying to show that increasing antenna size in an attempt to overcome "thunderstorm fade" was a pointless exercise.Scott in FL said:True, doubling the size of the reflector will increase the antenna's gain (and therefore G/T) by 6 dB, but it only works to a point.

You state "no loss of picture" which is good, so signal drop should not be a concern.ub1934 said:We had some heavy rain come through here in the North East and we (as we always do ) lost 99c/s & 103c/s , 101 , 110 , 119 all will drop to the low 60s to 70s & no loss of picture , without the rain 99 c/s & 103 c/s all read low to mid 90s with some 100s so what else can i check to stop this , Thanks![]()
With Direct's integrated triple LNB for MPEG4, you can't got a larger dish. Nothing else works since their dishes are not standard shapes. Put up a 6 footer with the triple LNB for 99/101/103 and the sigal will be worse.davring said:Not much, a much larger dish is really the only cure, and I mean a MUCH larger one. Rain can knock out any signal if it is heavy enough.

What are the dimensions of a Slimline 5? That's an elliptical reflector, correct? That makes estimating its equivalent diameter difficult. But here's the equation:tuff bob said:How much gain do you think the 1.2m DirecTV dish has over the slimline 5?
since the 1.2 is used with 110, 101, and 119 sats it would be useless for 99 or 103tuff bob said:22.5 in. x 32.5 in.
Obviously by buying the DirecTV 1.2m (Alaska/Hawaii) kit, the lnb should line up nicely with the reflector
Now that we only need to see 99-103 in HD-LIL markets, I'm wondering whether the 1.2M kit is worthwhile to cope better with rain fade
