More Cozi fun

[billyboy_1]

thanks for the update billyboy_1. I see what you mean about the feed/lnb mismatch. there are so many different interface flanges. my suggestion is find out your antennas exact model # or part # (is the sticker on the back of the dish legible .... if so post a pic here). here's a good thread for you to read. http://www.satelliteguys.us/xen/threads/rebuilding-an-prodelin-andrew-1-8.326064/

look for a factory feedhorn for it. ok i was nice & did some searching for you (you're welcome ... its in the thread listed above btw) these guys sell prodelin stuff. https://www.sateng.com/satellite/receive-only-feeds/products.aspx

you can never have enough of those prodelin 1.8's (even to have spare equipment) so go get the EJ dish.

Thanks for the help beavs. The best I can tell from doing some research is that the antenna is a Prodelin 1194. The ku receive only feed for a 1183 looks like it would be just right for this antenna due to the fact they are the same reflector. Thanks for the link.

you probably already looked @ this but in case you havenèt look @ attachment it helped me differentiate between models. note how there is two versions of the 1.8m dish. they have different physical dimensions & offset angles. there iséwas a 1184 model also which is a céku 1.8M txérx. good luck!

I'm having some minor problems with my multi switch/diseqc setup. Two of the three receivers on the system won't show any signal on a given satellite unless a certain one of them is on that same satellite. Can someone point me to some good reading on this type of setup. Previously I was using a 4x4 multi switch and had no problems.

If I disconnect the first receiver (far left diseqc) the other two work correctly.

I have couple (one installed another not) of exactly same dishes. Those are great ones. But you better separate hardware (dish, mount, LNB) from diseqc part.
I have friend who could adjust any universal LNB to original Prodelin feedhorn, that would cost you shipment across the pond and some money for machinery he is going to use to make flange.

Substitute that receiver into another 'slot' and/or substitute another receiver into its 'slot'. (Try to figure out if it's the receiver or the switch)

That is the exact same one I have. I believe it to be an 1194. The 1183 is the same reflector but the feed is different.

Fatair I have switched the receivers all around. It is the same situation. The receiver that is connected to the first diseqc switch (far left) dictates all the other ones. I must have something wrong with my configuration. I have tried different settings on the receivers and still have the same issue.

I do not really care about exact model of dish 1194 or 1183, as far as it's main mirror is same. Anyway, I fabricated feedarms to make this dish more multifeed-friendly.

Very nice. I like your fabrication. Looks great.

Think now it has to be one of the switches.
You'll probably have to bypass all diseqc switches and run all 3 receivers into each multiswitch dirtectly to check their operation.
If that doesn't find the fault:
Take one of the diseqc's out, one at a time, and run the receiver that's used by it directly to the multiswitches (also one at a time). Think it should 'hickup' when the bad switch is still connected. Operate as it should when it's bypassed.

Trail and error. Thanks I will check them.

 

[billyboy_1]

I went back to the 4x4 and have 2 sats on 3 receivers no problem.

 

[FaT Air]

Trial and error not. Just simplifying it to make sure it works in that configuration, then adding complexity, a step at a time, to determine when it stops working correctly. What was added to it that causes improper operation is the cause.

Try each multiswitch with all three receivers -

I re-read my previous post and the second part should have read
If that doesn't find the fault:
Add the diseqc switches, one at a time, and run the other receivers directly to the multiswitches
Think it should 'hickup' when the bad switch is then connected. May be a particular port on one of the diseqc switches.

I found this RX only feed and it matched up perfectly with the C120 LNB. This feed was on a 1.2 meter antenna. So far this is the best signals I have seen while working with this antenna. Even better signals than with the feedhorn that was on it, but that was a TX/RX system.

looks similar to/like a Invacom TWF-031 (umiversal)
Whatever works is rule #1. Nice bracket fabrication.

Yes that's correct a TWF-031. It didn't match up with the feedhorn that came with the antenna but I found this one and fabricated that bracket with some EMT from the local electrical supply store. Really happy with the signal levels now. Thanks for the comment.
