thinking outside the box with GeoSatPro Ku PLL LNBF
Well, a couple of units are on the way - thanks, Brian.
He asked me to post more info, so ...
Here's what I was thinking:
1). ... it might be possible to machine off the rings of the scalar, and bolt to the remaining flat disc/rim.
That might work to put the LNB on a Primestar feedhorn!
Could also mount the PLL LNB to recycled DishNet oval feeds for use on elliptical dishes.
Or, on DirectWay feed for their dish.
Eg: Primestar 84e, Prodelin 1.0 meter, etc.
I am usually looking for multi-receiver solutions, so one-output LNBFs don't generally draw my attention.
But for 80-90% of users who are using a single receiver, this brings a Standard PLL LNB to their unique feedhorn/dish combo.
2). ... actually, it was a desire to find a PLL solution for the orthomode feed , that got me here:
If an existing & inexpensive PLL Ku LNB could be adapted, would that result in more than just bragging rights?
Again, the scalar rings would need to be machined off.
Then, the round PLL LNB port would need to be mated to the standard rectangular port on an ortho feed.
You find those adaptres on Andrew/ChannelMaster/Primestar/Musak/Prodelin dishes between their feedhorn/scalar and a stock Ku LNB.
That configuration is for when a single polarity is sufficient.
The adapter is the wr-75 c-120 wave guide.
I don't have any; if anyone has a couple they could spare (normally pretty useless) I would appreciate.
Using two Standard PLL LNBs on an ortho would require a multiswitch, as always.
There might be several ways to go about this.
If done right, no switch mods would be needed.
But if the multiswitch had been altered to put out 18v on both inputs, rotating one of the PLL LNBs should fix that.
Might even be a better idea, if voltage drop on long coax was a consideration.
Right now, these are just ideas and questions.
I need to see the actual LNBF and talk to my machinist buddy to see what is possible and practical.
If it turns into a big project with pictures, I can start a new thread .
But for now, I hope questions and comments will be welcome here.
