[TowerTalk] Re: G-800

[Mike Holley]

As I plan to replace the destroyed (Now R.I.P.) G-800 rotor with a resurrected
and restored elderly HAM IV rotor I would also like to know if this rotor will
be capable of servicing a full size 20 mtr mono band (HAM-PRO H20-4) Similar in
size to a 204B .
                                           Thank you Mike VE7AVM
