The st 4 came in some suit cases, I used mine with an outback antenna. The bad news is it was stolen. I bought another system and it has an st 5 in the case. my plan was if I could find an st 4 I would leave the system intack oter wise I am going to use the astro d, which works fine, in my jeep wrangler. This would give me ten meters and cb. I have 3 of the 150a ubits, all need work. Also have you ever seen a mobile mount for the 150 or astro d?
