Help ID this Norsat LNB or LNA?

[Jullius]

I pickedup a 90cm dish today (will post pictures of the dish soon) with a norsat 2000 A Ku - model # EPS-020 LNB on it. Or is it an LNA? I'm out of my league here. Just wondering if this is useful as all for KU reception or not.

Thanks

its a LNBF but if I remember right, it may be one polarity only

I had pretty good luck finding out about a norsat product by emailing their microwave products technical support address.

see

www.norsat.com/support

Using the info on the LNB label, I asked them for a data sheet .

Really?

Using that info, what would you suppose the noise factor for a norsat 2000 A Ku - model # EPS-020 LNB is? 0.0dB?

In other words, that link appears to cover the following models:

2 +(7|9)+(07|08|09|10)+(A|B|C|D|K) eg. 2707A

Don't see anything about EPS-020

I use one a lot like that for sat 83 RTN. It is only one polarity. But it works well.

Single polarity WR-75 flange. Looking at the feedhorn, it may be designed for single polarity as well.

Does that mean it can be V or H but depends on how I skew it? I was actually thinking of using it for 83W as well.

 

[Mr Tony]

yes it works with either H or V depending on which way its skewed. You would turn the LNB 90 degrees to get the other polarity

Use your hands to change polarity. The neck of the feed will probably turn in the holder when the screws are loose.

It would be a good choice for that application. Seems to me that most of the stuff worth seeing on that bird is horizontal polarity.

What I did was to use the color bars on 11775 to get the dish alignment and skew close. Then switch to the RTN freq and twist it until you get the best signal quality.

If you are still having trouble seeing RTN then (as many people do) you might also fine tune the dish alignment using the RTN freq in your receiver.

Some people will say that you need a bigger dish than 90cm. But I get RTN with a 87 CM ADTH dish. YMMV

I get RTN just fine (70 quality) with a Winegard 76cm dish
