UPDATE: After finding out new info, if you Ku side don't work try the other setting. If you have a standard try Universal and vice-verse, we have learned that several of these units have been mislabeled
A few days ago I got in a shipment of the new NS-741’s from WS International. The first thing I noticed right off is that they do not come with the built in switch like the DMX741s. They also still have the bright orange Ku LNB, just like the DMX741s. Also the box says Circular and Linear however they did not include the plastic insert to use them for circular. This did not bother me as I myself have no need for it, however one of my customers might.
Also included in the box was a jumper wire, which is not needed since there is no built in switch. I have since been informed that there was a mistake including the coax jumper and not including the circular piece….Which has now been corrected.
Another thing is these LNBFs have a small raised lip around the edge. I didn’t think much about it until I tried to install one on my dish. I had a problem with it in testing, which I will get to in a minute.
Ok so I decided I wanted to test out one of these, new C/Ku LNBF’s in case anyone had any questions for me. I wanted to be able to say I had hands on experience with it. First thing I did, was go out and make sure my dish was peaked for optimum using the LNBF that was on it, a GEOSATpro C2.
I decided to test it on 103W, AMC1. The dish I used is a 10 foot Uni-mesh. I got out my notebook and chose which active transponders I wanted to use. I started with the C2 and using my satellite meter and my microHD, I took note of reading on different transponders and wrote them down.
On to the NS741….I removed the C2 and got ready to install the NS741 and discovered it will not fit in my scaler ring??? My scaler ring is an original Chaparral that has the recessed hex screw to tighten up the Feed Horn. I was up on a ladder and at an awkward angle. So I thought I am not getting to it properly. So I got down and re-positioned my ladder. Nope will not fit! The lip I mentioned above was causing it to be too wide to fit into the scaler. Note: If you use the scaler that comes with the NS741 you will not have this problem. So I sat and thought about it a minute and thought, nope not changing out my scaler for this test….sooo….I went to the shop and fired up the bench grinder.
With Lip removed I installed the NS741 onto my dish. It took a few minutes of not getting a signal on my meter to realize something else. On the top of the Ku Orange LNB there is a little scale just like on the DMX741’s. Going like this 30.…0….30. The DMX741 needs to be at the 6 or 12 O’ Clock position to be installed properly….Which makes sense, putting the “0” at 12 or 6 O’ clock….The NS741 needs to be, I found out, put at 9 or 3 O’ Clock position.
After I figured that out and fine-tuned it in the scaler, I proceeded with my test. I was pleased with the results. I have included a PDF file with my results. The NS741 performed almost identical to the DMX741. The NS741 actual performed a little bit better than the DMX741. The C2 by GEOSATpro was a little better, but that was no surprise.
In doing this test on 103W C-Band, I tested 3 different LNBFs. The C2, the NS741 and the DMX741. As I said the C2 performed better, but really wanted to test the difference between the two 741’s. I did not test the Ku side of this LNBF yet…well I did briefly to see that it was working and it did, I got the “surfing” channel just fine.……but my main testing with this test was how it did on C-Band. I was going to test the Ku side next to the Ku side on the DMX741 today, but it has been raining off and on.
Ok here is pictures of it and my attached PDF file. I will try to do some more tests soon.
