    My Satellite Setup:
    Strong 4375 driving 1.8 C.M. offset + Inverto Black Ultra twin + 2 BSC 421 C band l.n.b.,s - DR HD F15 - TM5302 and Skybox/Openbox M3 - HD receivers. - skystar 2 pc card - + other dishes in use - 2.4 CM offset - Alcoa 1.8 P.F. - C.M. 120.
    My Location:
    north west yorkshire
    Using the 1.8 to check those transponders i get 8.7 - 9.db on 12245 H and
    on 12054 H i get 0.0 to 1.0 db ..... but if i select V i get a fairly steady 2.0 db :-lol

    i,m leaving the circular setup on the big dish for now - to see how much it is a time of day thing with the transponders i get there .....

    Hi -- B.M.

    I t looks almost unused ... will be interesting to see what kind of performance you get from that OMT ... have you got l.n.b,s that will fit on it ....

    I have something similar that came with some other kit years ago but i,v never used it as i did not have the correct type of l.n.b. ... must try and find it later and see if its the same .... i,d forgotton about it till i saw your picture :)

    Did you get the dielectric plate/slab with the feedhorn ?

    It's a cross-pol feed for uplinking, used in the late 90's, and would normally have been fitted to a 90cm CM dish. All decommissioned around 2004.

    I have the NJRC uplinking kit and LNBs in the shed if you are interested (all High Ku 12.5 GHz from memory but can check over the weekend).

    The feeds will work on all frequencies though.

    I wasn't going to try selling them to you as they are licensed products, but if you want the specification of the system they used to be sold as (a complete system )

    OK, the original system was Eutelsat approved (EA-V021), a cross pol VSat system using a small Gilat tranceiver (o.5W) and NJRC LNB on a 90CM dish

    Approval was removed around 10 years ago, but the Gilat equipment I believe was already out of manufacture before 2003.

    Successor (AN-3422-02) as per below

    Gilat Satellite Networks Ku-BAND ODU transmitter p/n AN-3422-02 noise converter

    System performance for approval.

    Average G/T - 19.4 dB/K , Max uplink EIRP - 41 dBW / 4 kHz

    Hi --- @blademedia
    I had forgotten about this .. :-doh ... i did set this up on the 2.4 one day at the end of november ..
    nothing gained though ... most transponders i tried were a couple of db down on my current setup ,
    the l.n.b i used was from an rather old co rotor that i have, and probably is poor compared to anything current ... i have borrowed(from Vipersan) another l.n.b. again from an old co rotor just to compare to the one i used .. but due to poor weather and work prior to xmas i,v not had time to give it a try ... things happen slowly here sometimes :)
