My dish with 4 x Ku and 1 x Ka LNBfs. The 28.2E is on the west (left of image), and the 9E is on the east (right of image), due to reflection of dish.
Ecowitt weather station is actually on same pole but higher that it seems. The tall pole with a cable is a washing line next door behind us and it's higher ground.
That's a 6.2m CB aerial (Albrecht) behind for workshop CB. The proper radios are in the house (3.5m vertical on chimney and 22m long wire to front gate flagpole (not needing planning permission!).
Closer view
Sorry very silhouetted. But the Ka band Dual LNBF (not a Twin) is the most normal looking.
Some of the Quattros are Alps with a dielectric focus, others are Triax with the common Fresnel ring/small horn final focus. The Ku LNBFs and dish are nearly 17 years old. I had to replace the multiswitch a few years ago due to a leak in the shed roof.
Just pics on an old phone. A quattro (or dual) rather than quad or (twin) has each polarisation and band on a separate connection, rather multiple identical signals so the IF signals can be split to to feed up to 1024 outlets via cascaded multi-switches. I designed a system that could feed two satellite connections, TV & Radio, Cable TV and two DOCSIS broadband services on one pair of coax to up to 512 outlets.
I only have 12 outlets at home, but each cable in the house has three way diplexer to split satellite, radio and TV. The TV aerial, technomate HDMI to DVB-T modulator and radio aerial are combined in the attic and feed on a coax out in the shed where the multi-switch is. The system can also use the fibre LNBFs or single coax multi-satellite LNBFs (favoured by Sky now), via add-ons. I've no Sky box or freesat branded box now, but because the default is to feed LNBF #1 if no commands are sent, the #1 is 28.2E, so a Sky box or Freesat box would work. The #2 is 19.2E, #3 is 13E, #4 has three cables from 23.5E and one cable from 9E (Ka), so I don't get all the channels on 23.5E, but get the Irish channels instead on that LNBF setting on the setboxes or TV.
I could also feed in an analogue modulator or two as all the "digital TVs" also have analogue tuners. I gave away the Humax Freesat recorder as it was a pain on other than Freesat and would only record freesat. My cheap €45 to €90 (combo DTT + sat) boxes all record on USB sticks or USB HDD and the resulting files play on any laptop/PC/Tablet via VLC. They work fine with Freesat & Sky FTA channels, though only now/next EPG. Full epg on German stations. Some even take a Conax PayTV card (legally possible to have EU subs) and have built in WiFi (not used) for streaming. A few have Ethernet. All have SCART and some have audio + composite on a 4 pole 3.5mm jack, and that feeds the cheap MP3/Phone FM transmitters for car radio to give a few extra FM radio stations in the house. Power consumption less than 12W each.
