Jim I had similar doubts before I decided to my tower as a shunt feed.
I have only one tower and all antennas for 10 bands are on it. I have X7 with 2
elements for 30m above it 7 elements
for 50 MHz on 8 meters boom. On the level of 18m I have 2 elements wire delta
loop for 40m and 2 half slopers
for 80m. As you see many antennas and wires ...and the shunt feed tower is
working very well...for 3 years I worked
10 new ones (to #290). So ,the best idea is just to try it...
