So my mobile project is back on. I decided to retire my low miles 2001 Expedition. Not because of mechanical problems, it runs fine but needs paint. So I found a 2013 with great mechanical s and paint is fine, within my repaint budget. So off to the races.
The roof on the XLT model is 104 inches of genuine US Steel sheet metal front to back. Centered on this roof I plan to have a 6 meter antenna , NMO base loaded type. And fore and aft of the 6 meter antenna an 11 meter and 10 meter, also base loaded NMO mount. Assuming this geometry, the 10 meter and 11 meter antennas will be mounted about 52 inches from each other, and the 6 meter antenna 26 inches from the 10 and 11 meter antennas. (There will be various VHF and UHF NMO's interspersed. Of the V and U, I don't anticipate much interaction.)
What kind of interaction should I expect with respect to VSWR tuning of these three antennas, 6, 10 and 11M ?
Will I be playing Whack-A- Mole? Tuning strategy?
