Good choice with the Alpha -Delta!
Because living where you do, You may want to order some replacement ARC plugs to have on hand in case a high static charge pops one.
Just the layout design of the Alpha -Delta switches having all coax connectors on the top makes it a great choice aside from the build quality.
This lets you set it on your desk top (or elsewhere) and route the coax cables straight to it without having the typical Y shape configuration of nearly all the other switches. I never liked having coax cables coming to a switch from 2 different directions.
You'll notice the switch quality on the Alpha-Delta is smoother and lighter feeling compared to the typical heavier and clunkier metal ones. I've never had an Alpha-Delta switch fail but I had a few metal ones do.
A patch panel is good choice for multiple radios and other RF components if you do a lot of manual repatching if you want all coax cables routed to one place.
However, you can set up multiple switches to do the same without repatching cables.
Use one Alpha-Delta switch (up to 4 inputs) for all the radios and send the output to an RF amplifier, SWR meter, tuner, etc in that order, then route that as an input to another switch box for all your antennas connected as outputs.
MFJ made a desktop switch box which did the same to let you easily select any 6 RF input devices to any 6 antennas in just one box. It also had a common line so all connected RF devices can acess RF accessories such as a tuner or SWR meter. Good luck finding one of these.
