I've done a bit of reading on G5RV's and I plan to just use the
standard configuration of a 102' dipole center fed with 32' of 450 Ohm
ladder line.


According to EZNEC, here are the 50 ohm SWRs that you will
encounter if your 450 ohm ladder-line has a velocity factor
of 0.9. 3.8HMz, 17:1 7.2MHz, 4.8:1 10.125MHz, 55:1
14.2MHz, 2:1 18.14MHz, 35:1 21.3MHz, 23:1 25.95MHz, 2.5:1
28.4MHz, 60:1. You will definitely need a tuner. One wonders
if you couldn't do better with ladder-line all the way to the
tuner.
