[QUOTE="Vipersan, post: 744582, member: 325666"] Hi friends .. First ..appologies if there are any typos.. I will correct any I spot. My hands have been less than useful over the last few days ..making work and play very difficult .. Hopefully this is only temporary. OK hands up anyone who has taken apart an ALPS ku lnb..? Well I bought a couple cheap to 'experiment ' with.. ..and was surprised at its construction.. Once opened you realise there is an incredible amount of wasted space ...so closer mounting to the focal point on my pf dish is a definate possibility.. An even smaller hole cut in a C-band scalar plate than expected ....is on the cards Even better ... The lnb has a tiny concentric ring feed built onto the lnb feed end ...made of dielectric material.. So ..this is even more useful for prime focus dishes. I thought the bullet shaped plastic nose of the lnb might be essential to function .. So I tested a complete unit .. Then a stripped down unit .. The difference in gain on my selected test channel BBC NEWS @1West .. .......NONE... So ..it can be re-housed in a slimmer package ..and the concentric ring feed but to good use.. Below are the first pics Which include a picture of the received test channel .. A complete ALPS and a deconstructed one .. The lnb internals are currently wrapped in masking tape and an outer layer of aluminium tape .. ..and lashed to the C-band assembly with elastic bands .. Accuracy is paramount as the focus is critical ..but once on target the gain rises dramaticaly. More fun to come with this interesting lnb ..and at 6 Euro ...certainly inexpensive enough to carve up and play with. rgds 2 all VS [/QUOTE]
