I have been licensed since 1975 and operate HF from the base and mobile. Working DX from the mobile on 40 m is especially fun for me.
My rig is a TS-50 that does double duty as the mobile and base. I just run 100 watts which makes the challenge and fun greater!
The mobile antenna is the Hustler RM series antenna with 40 m, 20 m, and 10 m resonators. I have worked mobile to mobile DX to Europe. I am still looking for a mobile to mobile contact to VK or ZL.
My base antenna is an inverted L made from 26 gauge wire to keep it invisible to the neighbors (I live in a deed restricted community) at about 12 m. It is end-fed and I use a tuner to operate 160 m - 10 m.
