Keeping rain fade to a minimum

[tvropro]

I'm new to Direct but not c and ku band. Wanted to share my idea and solutions I did to minimize rain fade.

I currently only have SD with a D-11 but the idea's can also be used for HD with multiple satellites.



First thing I did was install a Slimline dish vs the 18" and modified the feed support to handle the single 18" LNBF.

Next I peaked the dish for maximum signal on all active transponders. 95 to 100 signal I'm showing.

Then I built a lnbf rain hood to shield the lnbf from rain drops getting on the lnbf lens. I used a paint can top for the hood and attached it to the lnbf (see pictures)

In theory the drops of water on the lens and clouds saturated with moisture cause the most attenuation on the k band signals.

So far pretty good results. Those who like to tinker may want to try some stuff themselves.

Quick question, IF you HAD a Slimline, why would you change it, why would you adapt anything, the 18" one gets the 101 only.
The Slimline you put up also gets the 101, put the Slimline back together and enjoy it, in the future you won't need to change your dish, until they change design again.

Fwiw, it's not the water droplets at the dish/ LNB that cause rain fade.
It's the disturbance in the storm clouds that keep the Sat signal from getting to the dish/lnb, nothing you can do about it .....
A LARGER Dish to capture more signal would be the only help.

I like what you've done with the LNB there, good thinking!

I got from the installer the Slimline but he didn't put it up, he hooked it up to an 18" DSS dish. He also gave me a Eagle Aspen 3 sat LNBF for the slimline. When I go to HD all I need to do is toss on the other LNBF do some realigning and hook up a HD receiver. Actually I may look for a bigger dish then the slimline if I go HD. I learned a long time ago especially with ku when it comes to rain fade the bigger the better.

dave,think about it, he took apart a Slimline that gets all 3-5 sat positions and adapted it to a 101 only, what did it do for him other than eliminate the rest of the sats. seeing the slimline already gets the 101.

Nice to play around with dishes, but lets make them BETTER not the other way around.

On the Eagle Aspen SL3 PIG-P is 101 at center? And will my D-11 access that LNBF in the menu? Curious

I love to tinker with dishes it's part of the hobby
