Nice! Looks like you have it all covered and then some. Very compact, well laid out monitoring station with some of the best scanners available of all time! I'm glad you're satisfied with the Diamond D220R antennas, 3 no less!OK The white airband antenna on the wall is working great on my 536. The Little Discone (I have 3) on the other 536 is pulling in local and New York stuff. Works Great. The Inflatable Air Antenna is on my V71. All the other radios are running through Stridesberg splitters not shown to 2 D220R discones mounted on the back of an ac unit outside. I am very Happy with the way they perform on interopt and state pd freq's. Coax is from a spool that a friend had. I just used what i needed and sent the rest back to him. I have various moble antennas scattered about in window sill's all around the apartment for my Ham radio's and aprs radio. Considering where i am at sea level the magic still happens and i get almost full signals on everything i listen and talk to.
