    I didn't have any instructions and no idea if the mesh was installed correctly when I collected the dish. It just got installed as best that I could. I doubt I had it installed with enough surface accuracy to be any good at all on Ku band.

    The LNB was a cheap (around £50) with the lowest noise temperature I could find. At the time, there were very few good C Band LNB's around as the only thing that was commonly received was the Russian 14W transmission that could be received with a dustbin lid.

    More work done today picked some 8.8 M16 high tensile nuts bolts and washers up put a couple of braces on the main king post and welded the leveling plate to the top of the king post.

    Managed to finish one part of the hinge system today a fair bit of work involved in this part i am glad to see the back of it tbh, the main bolt that holds it all together is M24 8.8 grade with a breaking strength of 32.5 ton-force metric so it shouldn't be going anywhere the four M16 8.8 grade give a combined breaking strength of 54.4 ton-force metric.

    Stainless bolts are good for no rust but they are weak in comparison to 8.8 grade and above i will grease them all up on completion.

    Hi more work done today,

    I wasn't happy with the king post there was a little bit of twist in it when the pivot was in the horizontal position so ive beefed it up by doubling up on the H girder and welded it on, next job was strapping some of what ive done to the rail track, still lots more work to do but a couple more jobs to tick off my long list.

    Ive seen a modification for the above feedhorn called the Frankenstein Triple (many thanks to the designer of this modification and documenting it)

    Anyhow i had a few spare parts knocking about to do this conversion, basically you do away with twin KU band LNB and use a universal one, i just need to cut the long pipe to length and insert it into the barrel tighten the grub screws up job done, i will finish it at some point tomorrow and post a few pictures up.

    On closer inspection it wasn't as simple as that the tube was about 1mm to big and wouldn't fit up the throat of the feedhorn, i am desperate for a lathe and been on the lookout for one for months now, i just cant find the right one at the right price local to me, so a little improvisation was needed,

    Job done that's KU band sorted

    Here is a link to this modification, Pendragon has done various modifications a man to look up to and take note,
    Frankenstein Triple Ortho or Dual Ortho Universal

    And here is another nice modification from him, its certainly worth time finding more threads by him and having a read through them.
    C-band Linear/Circular Orthomode Feed Modification

    Nah, interesting reading though. I don't do much on Ku at the moment, i have a 1.2 CM that i use if i wanted to wander off onto Ku lol.
    I just use my 2.2 for dedicated C-band and my other interest is Ka band for which i use a 1.2 Gibby with a motorised lnb changer for the different Ka bands. Was going to upgrade the Ka 1.2 Gibby to a 1.5 Gibby this summer but never got around to doing it - iv'e got too many irons in the fire as it is.
    I'm still interested in any info or quotes you get back on those full range Extended C-band lnb's though ;)

    I thought you might have got tempted pal, @lincsat had a nice 1.5 for free if he still has it and your in need ? pickup from Lincoln,

    I checked my emails regarding the LNB and nothing from them today, if i don't here anything tomorrow i will chase it up again as mentioned i really could do with one myself.

    Ok Mart, is the 1.5 an offset ? - needs to be an offset so as to install the lnb changer system and also a decent quality one like the Gibbys, which have a decent surface accuracy that's needed for Ka use.

    Yes John its off set and good quality if Ian still has it, a 1224 will bolt straight onto it but i have that, i would have had the dish but not having a van the quotes i got was not worth my while, Ian will look in at some point and let you know if its still available.

    Yes the dish is still available, it's laid on it's back and full of water ATM. Be quick though, the boss wants rid and it could get dumped before long.
