[TowerTalk] HAM IV Height

[Steve Dyer]

I just put the Orion in my LM-470 and it fits perfectly.
I wish the 2800DXA fit as well in my WT-51. I had to bend the rods out 
to clear the protruding "knobs" on upper rotating bell and now cannot 
fully lower the tower.
If Tashjian had welded the rotor mounting plate pins with that rotator 
model in mind (I told them I was using a 2800 when I ordered the tower), 
the 2800 would fit perfectly as well. I didn't know any better. Live and 
learn.
73,
