Because those are C-Band LNBFs used on a small offset dish, the angle they need to be at makes them fill with water. So there are some homemade caps to keep the water out. I would also locate and drill a drain hole on those LNBFs.
The LNBF's themselves don't look like anything special, you should be able to do the same type of mods to LNBF's available here in the states.
The first piece they insert in the LNBF throat looks like a dialectric plate to get circular signals, pretty much useless for most FTA over here. The other two there's no way to tell how good they're without knowing about the TP's they're aiming at.
Good afternoon. Happy New Year.
Thanks danristheman and KE4EST that helped to find this topic.
This LNB, the range C. With its depolymer I experienced.At us, this LNB works well with frequencies, circular polarization-R and L.
And you have all satellites, C range, linear-V and H.
Inside the LNB, Alyano depolarizer shtirevoy.Stoyat rivets iron.
My friend from Western Ukraine designed better LNB than Yaliano. With water pipes and a plate-cross.
First a few photos of the LNB Alyno.
This modified LNB works on small Dish, 0.6-1.2 m, the opening angle is 70-90 degrees.
My friend Vitaly from Western Ukraine has passed here such a modified LNB. This plate is a cross, you can test it at yourself. To do it, I'll write below. With LNB, take out your native plate and put a new one. The result is excellent. Started with 5 photos.
The guys from Siberia, instead of the native plate, put glass. The thickness of the glass is 4 mm, the signal is slightly growing.Photo-11
Gave me Vitaly 2 irradiator. One already did it myself, not difficult.
I fixed the signal on my antenna. I measured the signal. I removed the standard plate and the pancake. I tested a new modified LNB. I had excellent indicators, almost twice the signal was stronger. It only bothers with snow and some water. It is necessary to put a plastic case.
Has fixed LNB and on the motor, the aerial 1,1m. Almost all satellites have caught in With gangs.2 photos of the last.
