I had a new Geo SL1p that I never used because I discovered my 6ft prime focus dish was warped and took it down.
So I got to thinking how it would perform on a offset dish. I pulled the nose cover off, and sawed off the throat and filed it even with the scalar rings. Using a feed horn from a Channel Master 1.2m dish with a C-120 flange as a guide, I marked, drilled, and tapped four holes in the scalar ring. (you could substitute nut and bolt if you don't have a way to tap threads) Then applied a little RTV silicone seal to keep the weather out, and bolted the C-120 flange flush against the scalar ring with the 18mm throats lined up. I decided to do a comparison of the GeoSatPro SL1p against a Invacom SNF-031 and a Prime Star "pop can" NJR-2112F lnb's, all mounted to identical Channel Master feeds.
First up was the existing Invacom mounted on my 1.2m Channel Master dish.
I cleaned out all the TP's on three sats and did a fresh scan.
Next was the custom GeoSatPro SL1p.
And then the original Prime Star lnb.
Sat TP Invacom Q GeoSat Q Prime star Q
72w 11968 H 1666 72 71 71
72w 12148 V 2573 71 71 71
72w 11844 V 29657 76 76 75
89w 11989 V 4999 71 71 71
89w 11959 V 19530 71 75 76
89w 12173 H 11139 60 44 53
125w 12184 V 29997 76 76 76
125w 12039 H 3725 71 71 71
125w 12167 H 4443 71 71 71
average 71.0 69.6 70.6
Conclusion:
If you throw out the one low level TP from 89w these lnb's test almost identical!
Since the results are in close agreement even though using different priced and age lnb's it might say that the identical feed horns that match the dish is the key reason.
Anytime I've tested after market lnb's with their own feeds the results varied much more.
Good reason to use the original feed for your dish if available.
The GeoSatPro SL1p is a high performing lnb, and Sat AV sells them for $10. A small modification and you can have it bolted up to your original feed!

Anole,
I added a couple more players to the contest this afternoon.
I found one of your FSS stacked dish lnb's as well as a single polarity commercial lnb.
Next up was the Dish FSS that came off of a Dish SuperDish.
Then I mounted the single polarity commercial lnb. Had to scan vert, then come out and rotate 90 deg for the horz TP's and re-scan.
Sat----TP------------Invacom Q GeoSat Q Prime star Q Dish FSS Q Single Pol. Q
72w 11968 H 1666-------72--------71----------71-----------71-----------71
72w 12148 V 2573-------71--------71----------71-----------71------------71
72w 11844 V 29657------76--------76----------75-----------76------------76
89w 11989 V 4999-------71--------71-----------71-----------71------------71
89w 11959 V 19530------71--------75----------76-----------76------------76
125w 12184 V 29997-----76--------76----------76-----------76------------76
125w 12039 H 3725-------71--------71----------71-----------71------------71
125w 12167 H 4443-------71--------71----------71-----------71------------71
So even the Dish lnb and the standard Ku lnb delivered readings in close agreement.
The Dish L.O. was off quite a bit, probably why it was taken out of service, and with the stacked math you have to do for horz, I would recommend these except for a fixed dish you don't scan much. The single polarity is fine for a sat you only need one side such as 125w, not much on horz.
So if you are looking for a C-120 bolt up lnb, with a small modification the GeoSatPro SL1p performs just as well and is much cheaper than an Invacom.
From my own experience trying to mount an aftermarket lnb on a Channel Master or Prime star dish is a cobble job because the focal point is so far in front of the mount clamp. If you don't have one of these dishes you should.
1.2m dishes are all over the place on top of banks, gas stations, investment firms, all for the asking. Many are out of service due to networking of these places. The original feed is very good, and if you are not using it, you should. Get a C-120 lnb, or make one yourself. Easy!
Often, old commercial dishes taken out of service, have the feed with 'em.
If not, sometimes they show up here on the forum, Craig's List, swap meets, Ham conventions, or in certain trash cans
See also, the three links at the bottom of my post #10 (above) for info on making 'em out of parts you might have.

Very interesting thread and the results!!! Thank you for the great comparison! 
I was wondering if it would be possible to quaticise comparison between aftermarket LNBs used on the CM dish without and with the feed horn and compare for example:
1) Invacom SNF-031 + CM feed horn vs. 2) Invacom SNH-031.
How much difference (in % of the signal strenth/quality or dB) should one expect?
Thank you

I was having similar issues last night while watching and recording the NLCS game on 148. When I tried resuming the game at one point the screen went blank and I couldn't get my H3 to respond to any remote commands. Eventually the Hopper went to a HD channel but still no remote response. After a while the Hopper went into a re-boot cycle. This happened at least 3 times. I was using an IR universal remote only.
A little frustrating to have the game broken up like that but at least the Brewers won
Yea, I've only been a CIO for the last 30 years!
Trust me, when something important breaks, they get to own it!

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....

This started a couple months ago. I have 2 H3s on one network, both with 2 EHD identical 3 TB seperately powered so all recordings are accessible by all 4k & J4s (8 of them).
On one H3 (not the main one that controls the MOCA network), after it reboots, it doesn't recognize it has two EHDs plugged into it. Rebooting the EHD by their power source doesn't fix it. Resetting the network doesn't. Software h3 reset doesn't fix it. Rebooting MOCA h3 doesn't fix it but so far, after 3+ cold boots (unplug pwr to H3 with unrecognized EHDs), it finally it figures out they are plugged into it. BUT.... Then when you open a program it only partially shows series and episodes, but instead of showing recordings, it only shows upcoming airings. HELP!!!!

Thanks JohnGalt1234 - That's interesting. I wonder are the Boot Strap versions different between a Hopper 3 only and a Hopper 3 with Hopper Plus setup as I have the later. I guess when charlesrshell is able to since he has both setups, he can do the test. Unless the bootstrap version is tied to when the specific Hopper 3 is manufactured, in my case, mines is from February 2016 when it was installed.
At least Google Search AI is saying the bootstrap version will never change and unique to each Hopper 3.
This is probably why different people seem to either have the issue or they don't because the bootstrap code could also be tied to the hardware revision and
components other than the internal HD.

JohnGalt1234 - So you basically have 2 Hopper 3's. The CasinoH3 is the one that is Hopper 3 only while Master Bedroom is a Hopper 3 with Hopper Plus setup.
Master Bedroom uses Android TV (ATV) software so the DISH part is actually a app and will behave differently as you can probably tell the Guide's are different on the Master Bedroom which will resemble the same guide used on other ATV devices such as the Joey 4 and Wireless Joey 4. If I am correct, the CasinoH3 is the one with the problem since you did say the one dated 09/05/2026 is the naughty one while 08/15/2026 named Master Bedroom is the nice one. Usually I would expect the CasinoH3 to be the one without the problem because it's Hopper 3 only and Master Bedroom would be the one with problems because it has the Hopper Plus involved. That is why they behave differently because CasinoH3 is running the native Hopper 3 software while Master Bedroom is running the Android TV software and also it runs a app called DISH known as package com.dish.atv.launcher, the version for mines is P15403 2026100917 so it's probably the same version as the Hopper Plus software version with the date of October 9, 2026, not sure what the 17 means except maybe revision 17?
This explains it better than I can. Sorry, had to take all the ads out.

I was watching some of this guy's stuff and realized some of you may not be familiar. Basically his show is Candid Camera meets a magician. This is a comp of a few of his exploits. I first learned of him when I was out at a meeting in Denver about 10yrs ago. The men I was sitting at the table with started talking about this show and said it was one of the funniest things they had seen. When I got home I started watching it....yes, it is funny.

Anyone else watch this show? Any guesses as to what was in the box Gibbs gave to Abby that was on her desk? It look liked it was glowing.
I also heard that someone was leaving the show at the end of this season. Any guesses as to who thats going to be?

Tony as the director.
Would you rather have LaRoche ???Tony as the director.
No. Bring in someone new.
Tony is not serious enough for me. Parker is too close to the team and Tim is too young to take over IMO.
I don't think Tim and Tony are that far apart in Age ...No. Bring in someone new.
Remember what Tony said to Tim when they first got back together ...
Tony said: I am the New Tony, Tim .... (something to that effect)
Tony has changed, he's been running his Security Business ... I'm sure he has grown up.
Give it time ... your judging the New Tony from the old Tony.
It sounds like Tim won't be around the Team much longer either.
