- My Satellite Setup
- Strong 4375 driving 1.8 C.M. offset + Inverto Black Ultra twin + BSC 421 and Zinwell C band l.n.b.,s - DR HD F15 - TM5302 and Skybox/Openbox M3 - HD receivers.+ other dishes in use - 2.4 CM offset - Alcoa 1.8 P.F. - C.M. 120.
- My Location
- north west yorkshire
Keep on tryingYes, 38.0 East in C-Band certainly provides challenges and opportunity for experimentation for UK located DX'ers.
I decided to take the Titanium Wimax LNBF out of the replica ADL linear polarity pipe and secure it directly in the feed clamp. I got increased signals pretty much all round so decided to do a quick feed/scalar pair test with the LNBF throat aperture 750mm from the centre of the dish (focal length = 755mm).
The feed/scalar pair table from the test is attached below. There looks to be a vague trend whereby the lower frequencies require a longer scalar distance along the LNBF barrel and the higher frequencies do not like so much length. The length phenomena was observed for a prime focus dish, I am not sure if it would apply to an offset focus dish.
I am still sniffing after a lock for 4023 V (92 News) and was getting 5.0 db about an hour ago. If it increases as the evening progresses I might be lucky enough to grab a lock on it.

I.v been out most of the day so no adjustments made to my l.n.b. focus etc ...
I,v managed to take a few photos of some screens tonight though .... I,m still having to make slight adjustments to the AZ to get the best from some transponders.
