[TenTec] Jupiter Autotuner upgrade?

[John <jh.graves@verizon.net>]

I am considering adding the autotuner to my Jupiter.  My normal antenna 
for now is a G5RV with plans for getting my R-7 Vertical back on the air 
ASAP.  Other than making me feel better, what is gained by adding the 
autotuner to the mix.  The G5RV gets quirky to tune on 80 and 40 using 
my MFJ tuner. Will a G5RV be within the tuning range of the TT autotuner 
with these bands and antenna?  Any experiences are appreciated.
