I can see the video posted by FTA4PA but that's it.Slamming you? haha No, I was joking that you must have your ad-blocker or similar set too high.
Only other guess is you have the poster right after him, that posted the picture, blocked.

My first dish was a Radio Shack branded perforated 8 foot dish with a buttonhook feed and HH motor (wish they still made consumer grade antennas with those types of motors). All my other C-band antennas have been prime focus with 4 feed supports.
I don’t know about pigeons breeding in there but I do have a plastic cap on the LNBF to keep wasps/hornets/yellow jackets out
And in case anyone is wondering I posted a picture of my dish turned all the way East and the cats got on it lol
No kitties were microwaved during my FTA tenure
This is very popular. For example, Andrew 4.6m ground station is one of them (I have one). The most seldom is Cassagrain offset setup, this, as far as I know is really rare as chicken teeth. Only one company made one model long time ago and that was it. And I have it too, it is on my avatar.
You can't. You could possibly upload it to somewhere like imgur.com and send them the link to it.
Park your parakeet in front of your Viasat or HughesNet dish sometime and do some heavy streaming.Slamming you? haha No, I was joking that you must have your ad-blocker or similar set too high.

Makes for a nice afternoon tid-bit....once you get past the feathers.
RimaNTSS, thought your Andrews dish was a convex secondary. The big uplink dishes near here look like they use a convex reflector, unless that is just a radome, but not sure if there is room in there for anything. Next time in the area I might stop by and ask since I know some of the techs there. This is obvously something I have not paid that much attention to.
When at VLA, one of the guides mentioned Gregorian. Looking back at one of the pictures I took when down there looks like a convex sub-reflector, which would make it a basic cassigrain. Maybe there is some confusion in the industry regarding terminology.
Attached the image.
(back on topic) The button hook is a fine design as long as the feed support is strong enough to keep the assembly stable in high winds, ice accretion, etc. It allows adjustment of the scaler ring by moving the supporting pole in and out (most models) to maximize signals (focal depth). The feedhorn position can also be adjusted as with a tri-pod or quad-pod feed support. Some add cables or rods to further support the feed horn assembly if it's not a strong support. The button-hook dish I have uses several bolts in a hub to hold and centre the feed.

I upgraded my button hook feed with thick wall aluminum tubing. Very rigid now from the original. Just enough room in the bore to pass 2 pieces of coax through without F connectors.

Also keeping the support a bit to one side helps to minimize it's RF shadow effect.
Different manufacturers design the LNB support differently likely due to patents etc. As long as it positions the feed horn at the focal point. Bending the pipe might maintain strength while minimizing manufacturing processes.
