> Just got a CC XM-240 together and on the tower. I'm having some tuning
issues. There are CW, MID and SSB settings on the elements and I split the
difference per some of the other posts that I have seen between CW and MID.
80ft and using an MFJ-259B, the best I see is about 2.5 SWR at 7.062Mhz. I
see no other dips.
Hmm. I've got a lot of experience with the 402CD but not much with the
XM. My advice was to split the CW and MID settings. That way it would resonate
about 7.060 and the 2:1 points were 7.000 and 7.250.

The only difference in the 2 antennas is the fact that the reflector is
grounded in the XM version.

made an aluminum sleeve so that the tip would fit.
Don't know what else to tell you. It should show a big dip low in the

I am using the CC supplied matching network.
What is a CC supplied matching network? That's a new one on me. The split
coax feed was the last thing I saw.
Sorry I couldn't be more help.
