Substituting a Channel Master 1x0.7 dish for a Shaw 75E

[Bob Schaefer]

Trying to use a Channel Master 1x0.7-1 in place of a Shaw 75E. I have the dish but not the arm that the Mfg. supplies. Trying to use the xKu LNBF that goes with the 75E but having a hard time finding the sweet spot for the dish. Does anyone have any suggestions on where it needs to be mounted? Looking to pick up the 111 &107 birds. It should work, if I can just find the sweet spot.
Thanks

The 1x0.7 arm is about an inch longer than the 75e arm. I don't know of any other differences than maybe the lnb angle relative to the arm, though I'd expect it to be minor.

I figured out a way to extend the arm easily and adjustable. Tried it in several positions, but can't get a reading on my sat buddy. I'm thinking it has to be the angel. That or my LNB is dead.

A monoblock LNBF usually cannot be moved between dishes. The distance between the two LNBFs (signal convergence points) will vary depending on the reflector FD. Despite that, one Satellite should lock. The second satellite will be the challenge.

the part that bothers me. I can't get the 111 or the 107 to lock in. I get zip on the meter.
Thanks for all the suggestions!

Is the LO Frequency is set to 10070? The regular legacy LNBFs (not xKu) LO Frequency was 10750.

Ok so you have a rare skewable mount 1.0x.7 ch master with 6 deg spacing arm?.Can you post a pic?...

I hooked my Xku lnb to my azbox and scanned vertical for you. Shaw lnb's are boresight, so have to aim at 111. Strong TP is 11770 V 3270. These are the Live channels which are not digicypher. Setting would be 10750 (only 107 G1 is low KU band) and 22khz on.

This is what I am working with. I added the wood to extend the arm trying to locate the sweet spot.

The arm length on the 75E is 20 7/8 inches, so the approximate arm length should be 21 7/8 inches, if post #2 is correct

might want to consider:
Mini mirrors survey dish's geometry, locate focal spot
and a follow-up
Checking dish's focusing with mirrors and magnets - another version

Here're two pics showing some size information. This is a 1x0.7 lnb and arm.

From your pic, it looks like the lnb is too far away and low.

When I said the 1x0.7 arm is about an inch longer, that's a recollection from when I was looking through a pile of 80 lnb arms looking for the 9 that were for the 1x0.7 dish. the rest were about an inch shorter and for the 75e.
