Hi Tim et al,
The antenna I used yesterday was a modified MP-1 vertical as you see attached. The whip that comes w the original is 4 feet long. I replaced it w a military surplus PRC-26 collapsible whip which is 10 feet long. Not only does it radiate better but also between 17 and 15 meter bands I need not change the coil position. Another mod is using 3 sets of 15 wire computer ribbon cable , totaling 45, for radials instead of the original 4 sets of 4 wires which are very easy to break.
The PRC-26 is often offered on eBay for $10-20. There is one right now going for $10 plus.
I hope your recovery is going smoothly.
73,
