[Amps] Butternut HF9V: homebrew addition of 160 meters?

[Gary Smith]

Not sure I want to try 160M with my butternut. It's elevated 20' with 
6 radials for 10,15,20 & 40 and two radials for 80. Not exactly great 
for DX with no radials on 160 but I'm right on the ocean so it's 
worth trying something as I only have 58 confirmed on 160.

Anyone know a homebrew way of Adding 160 to this antenna that 
wouldn't require taking it down?

If worse comes to worse I can use a shortened loop antenna with vac 
variable & servos to get there (did that giving me most of the 58 
confirmed when I was living in Illinois). It would be more convenient 
having everything on the butternut.

The upside of the short loop was: I had full 160 coverage at 1:1 at 
full legal output.

Downside: the extra control wires, coax & need for an antenna switch.

Thanks,

Gary
