you more flexibilty. For example with my C4XL at 75' and a C3 at 45', I find the lower C3 works much better for domestic stuff. Then in phase, it really works the dx. I'm fixing to move out to the country and plan on adding a 3rd antenna, a C3E (I'll add the extra 10m reflectors to the C4XL and my original C3 in the field). I think multiple antennas are superiour. Now to Gary's question. If your going to go with one antenna to cover the 4 bands its tough to beat the C4XL. I have no experience with the C4SXL, but if $$ or size is not a problem go with the C4XL. Also, instead of using the tuner for 40, unless you already have one, get the 40m relay box that mounts on the boom. You then tune the 40m driver for ssb, when you switch the relay on it adds some inductance at the feed point and moves the reasonant freq down to the cw portion of the band. I have one but have not been able to get on the tower to tune the box for the cw portion. It looks like I need to remove a coil on each coil in the relay box.
