Dual Polarity for Muzak dish / flange?

I picked up one of those white Muzak dishes as referred to in this thread...

http://www.satelliteguys.us/free-air-fta-discussion/164553-new-dish-muzak.html

and am having a problem coming up with a good solution for converting the specialized feed to dual polarity. Preferably, I want to maintain usage of this particular feed horn as we're talking elliptical here.

Like a lot of these commercial dishes, the feeds are designed for use with block style single polarity LNB's with a polarity reducer. This 1m x .76m dish looks a lot like an updated Primestar, but unfortunately the LNB mounting flange used on the feed is NOT directly C120 compatible.

I've attached a couple of pics to illustrate. Notice the (6) hole pattern used on it's flange coupler; totally different from the (8) hole pattern used on the C120 (a Dish FSS LNB is shown for comparison).

Thus my question is... has anyone successfully mated a dual-polarity LNB to this style of feed horn??

Failing an elegant solution, I might have to come up with some way to clamp the Muzak feed collar to the Dish FSS, but don't know what problems that may entail. And I suppose if I get real ambitious, I might just drill (4) new holes in the FSS LNB flange using the Muzak collar as a guide and screw 'em together - but even then, I'm left with a cheesy mating right at the feed throat as evidenced by the FSS O-ring not mating up very well with a flat metal surface for environmental sealing. It sure would be nice if a proper mating adapter to a C120 were out there somewhere!

Has anyone previously conquered this conundrum?

you may be able to save money by just buying a 36 or 39 inch dish with lnb.
Ive also seen the invocom lnb sold that bolts up to a clamp and also you can buy the feedhorn for it. I have the other type muzak dishes with the 3 arms that come out and a clamp that holds a lnb. I was able to modify it for other types of lnbs.

Gettin' close...

What I've found is that the adapter/polarizer and it's hole pattern can be mated to the C120 flange - provided orientation is correct. If it doesn't match, try the 90-degree rotation trick and you'll get a (4) hole match up. That's a decent mechanical solution for any C120 LNB and since the original polarizer is still in play, the feedhorn assembly is also retained 100% - just what the doctor ordered for the elliptical dish!

But one problem remains... the polarizer still polarizes.

So, what I'm going to try next is a temporary NPM on the dish in the yard with this arrangement looking at (maybe) 97w and see what does and doesn't work with the dual polarity LNB and a polarizer downstream of the feed. (In time, perhaps I can have the polarizer bored out to the proper throat dimension, yielding a non-polarizing polarizer!

)

I've pre-skewed the LNB by 14 degrees or so which is what is supposedly needed for my neck of the woods if I were to target 97w.

Ya know... why don't the installers EVER skew their commercial dishes?? I've looked at several of these installs and they are oriented perfectly vertical no matter what bird they're looking at. Dish and Direct have to because of multiple birds scattered across the arc - but these single bird dishes like to stand tall and pretty, I guess. They must lose some efficiency along the way doing that...

That looks just like a Prodelin 1.2m I have. I would be most grateful if you would post a closeup pic or two of how you modified the original feed bracket to host the 40mm dia. LNB that was (teasingly) shown!

I think at that time I just used some straping with holes in it and put bolts through the holes in the strap and through the holes in the original holders bottom. I do not use that lnb any longer and have since went to this setup with 2 lnbs for 97 and 101.

The dish itself may not be skewable (usually the elliptical ones are), but if the dish isn't skewed, the LNB certainly must be if the dish is aimed at a satellite that isn't near true south.

Well, here we are!

97w is stable and active on the dish (which I guess is actually classified as an 84cm) - both polarities.

Getting started, SatMex6 was the first satellite I discovered with my cheapo sat finder and a bit later, I headed back east and ended up one slot past 97.0w, then finally settled in on G19 when I got around to doing blind scans on a decent receiver. My old favorite... a Coship 3188c, is presently suffering from leaky power supply capacitors and is out of commission for the moment. But a born again Coolsat 5000 did just fine as a stand-in and will be relied upon over the next day or two as I see just what effect the rectangular opening in that WR75 "transition" collar (aka. polarizer) has on signals of both H & V polarities.

So... for now the peaking remains to be performed but I'm happy that the mechanics of the feed coupler didn't throw too big of a monkey wrench in the works. :up:up

USA Healthcare Costs are Ridiculous

Pissed off at the crappy healthcare costs

My health Insurance renewal for 2027 just came in. Going from $827 a month to $1,187 a month. Deductible going up a $1k to $9,350. Max out of pocket also going up $1k to $11,000. Doctor co-pay of $40. Urgent Care co-pay $50. ER 50% coinsurance after deductible. That's all in network. Out of network is double, should it be needed.

Have to think about this. I'm really tempted to just go without now. I only go to the doctor once or twice a year. I pay out of pocket for Tirzepitide and can do without the Rosuvastatin (crestor) now. Really tired of spending over $10k a year and getting nothing out of it.

After years with Blue Cross I switched last year to Ambetter as my Blue Cross premium was going from $1200 to $1800 for a Silver plan and the Bronze plan was still going to be $1300 at BCBS. Ambetter was $827 for the same coverage with a Bronze plan. Didn't think it would jump this much so soon.

I'm guessing a Silver plan is probably over $2,000 a month for 2027.

Even sarcastically it's wrong. Undocumented immigrants already weren't eligible for federal Medicaid, so there's no one to "get off the rolls." The immigrant-related pieces are a small part of the ~$1 trillion. They cut the federal match for emergency care from 90% to the state's regular rate and end eligibility for some lawful immigrants like refugees. Most of the "savings" come from work requirements, more frequent eligibility checks, and provider tax limits, which hit citizens.

Either way, the cost doesn't disappear. It shifts to states, hospitals, and everyone else's premiums and will only serve to make issues like those raised in this thread worse.

That's only part correct. Actually I had to look it up to make sure. There is NO Federal money going to Medicaid for illegals but there ARE some states that use State money to pay for Medicaid for illegals. Here's the list

- California: Covers all income-eligible undocumented adults. [1, 2]
- Colorado: Covers specific adult demographics (with upcoming budget caps in 2027). [1]
- Illinois: Covers specific adult age brackets. [1]
- New York: Covers specific adult demographics. [1]
- Oregon: Covers all income-eligible undocumented adults. [1, 2]
- Washington: Covers specific adult demographics. [1, 2]
- Washington, D.C.: Provides adult coverage through the D.C. Health Care Alliance. [1, 2]

Fair point, but it's consistent with what I said: no federal Medicaid money goes to undocumented immigrants. Those programs are state-funded, so the federal ~$1T cut can't touch them. Whatever states decide to do with their own programs is a separate budget decision.

Song Name Game Part 3!

Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!

So let the game continue!

The last song was added by Bobby who posted...

One Meat Ball - Andrews Sisters

CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!

Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game

Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.

Example:

Long Live Rock and Roll -- Rainbow

Rainbow in the Dark -- Dio

Another example:

Ride the Lightning -- Metallica

Lightning Strikes -- Ozzy Osbourne

Get it?

An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....

Today is the anniversary of Dan Wheldon's passing at Las Vegas in a dreadful crash that luckily didn't take more drivers' lives. I vaguely remember the crash, but I more strongly remember Paul Tracy trying to keep it together as he left the Medical Center knowing that Dan most likely wasn't going to.

The safety in these vehicles is beyond incomprehensible, especially relative to what it was 60 years ago, when dying wasn't unexpected. But it is still very dangerous. I always scoff at the prayer invocations, but never scoff at the risks these drivers take and the emergency workers out there who might need to pull short of a miracle to save a driver's life.

HBO Max has the live in car streaming without commercials, which provides an interesting take, but you are driving blind, knowing only what the team is telling the driver about what is happening on the track. The stages definitely ruin the NASCAR set up.

NASCAR is an abject mess, but at least it has Kyle Larson. Guy had the lead on the green/white checker, fell back to 12th or the like, kept his cool, and charged back to win with room to spare at the line. And win very cleanly!

NASCAR needs to stop racing at Talladega. Especially if they are going for elderly Sunday drives at the track! Stage racing is real stupid, but NASCAR should consider one half point a second per group gap as a bonus.
