Thanks, The Maldol is a compromise antenna but performs well at 2/440. On 6m it is just OK. I'm going to try adding another diplexer to split out 2 and 6 from 440 and swap the Maldol for a Larsen NMO50 5/8ths wave 2m which loads very nicely as a 1/4 wave 6 meter antenna. I just need to punch a hole on the roof of the Jeep for the 440 whip when things warm up and I can find the time.
Thanks Dave, sounds like a great antenna set up.
