I'd use it for your one antenna, and have a coax-switch inside the 
shack, to fire off a different tx/rx combo into your all-purpose antenna.

the Johnson Matchbox will handle open wire line. 
Loop formula = 1005 / F(Mc)
L = 1005 / 3.9 (arbitrarily)
L =  ~258'
A 258' delta loop is 86' per side.
A 4-sided horizontal loop is 64.5' per side.

On your lot, I don't see how you could get up an antenna for 160m. (Even 
the two of 'em, side-by-side)

On my lot, the antenna is up, and has been used on all bands, 80 ~ 10m, 
with the 'tuner' (I hate that term - it's so 'wrong').
