John,

The CC balun is 1:1 but the XM 240 does not have any matching - gamma,
T, hairpin, etc.  That is why a 2:1 balun is a better choice.

I thought the XM240 balun was a 1:1?
The XM240 balun they supply is just teflon coax wound (4 or 5 turns I
think)around three ferrite cores
The older CC antennas used a coax coil balun and grounded the reflector.
