He finally had to go to a two tower array, another ground system, a phaser, a day night switching control and a lot of bucks for the owner. Station now are allowed lowering power to accomplish protection but back then it was 250w, 500w, or 1KW, etc. Nothing in between for a single tower set up. Now they permit single tower daytimers to operate at night with very low power levels as low as a few watts to keep their station on at night. I am sort of certain that some ham has modeled the pros and cons of a slant wire feed for a grounded tower but I have never seen such results published. Some hams tell me they do this to bring the feed wire into the shack so they can use the tuner there to get a decent match across the band.
