Norsat C-band lnbf

[lme]

Currently I have an old Norsat lnb installed on my corotor 2 system (see bellow pic):

I'm looking at replacing it with a Norsat 5150 RF PLL lnb, but I'll have to use an elbow to install it as to be able to cover the hole corotor system with the plastic cone.
Any inputs about this new Norsat ?

I have not tried one yet but I plan to order either a 5150 RF or an ESAT 2022-150 off ebay. The ESAT is $20 cheaper. (I need to compare the specs more first)
I have a cheap Chinese lnb that started to fail yesterday.

Ime, I purchased a Norsat 8525RF (DRO) instead due to the power requirements of a PLL.

Surely someone else can answer your 5150RF question.

I also found this DRO, (i forgot about it) a friend gave it to me long time ago:

I'll try it when the weather improves...

Looks like that 8115 has better Temp and Stability specs than the 8525RF I just bought.

BUT: The 8525RF only does 3.7 - 4.2 GHz. As I understand it, the 8000R series has terrestrial interference rejection to reduce interference below 3.7 GHz. So that is a plus at some locations.

The 8000/8000RF series is discontinued. I searched for a better 8000RF model, but 8525RF seems to be the best of the 8000RF series remaining in stock.

Hope it works well for you and I look forward to reading your results.

Well, DRO doesn't do any good: loosing ~3dB, maybe due to the elbow i need to insert it, so i can fit the cover over.
I'm back to my old lnb from post #1.

[armadillo_115]

While you had the cover off, did you test the DRO without the elbow?
That way you would have an idea how well the DRO works without an elbow. (for future reference)

BTW: My 8525RF was due today.... but got 'delayed' in New Jersey. Whatever that means. Maybe the foreign country of NJ has Customs. lol

When comparing pll and dro lnbs, there should be little if any signal difference provided the lnbs are of same or similar quality. A pll may perform better than a dro in instances where the signal is weak and narrow. The signal difference between a dro and pll should be similar on satellite transponders with video.

Providers named DishNetwork, Bell, Shaw, and Direct all use dro type lnbs. All of these providers would switch to pll type lnbs if there were a great signal advantage to them.

I suggested testing the DRO (without elbow) because a friend gave it to him long ago, and was probably of unknown condition.

My 8525RF arrived, installed, and in testing today.

Edit. Forgot to add: My 8525RF is replacing the same model lnb (8115) that Ime just had up. So far the 8525RF seems slightly better at locking that darn Panamericana channel. Time will tell.

no elbow Vu+ gets same sig strenght as my very old norsat, but osmio shows same lower values as with the elbow.
So I'm back to my old norsat as i do not see any improuvements from dro.
