[Towertalk] C.A.T.S./Rotor Doctor RD1800

[Frank W8H0]

Hi Dave and Others on TowerTalk,

The rating sheet on the RD-1800 shows that it's measurements will fit into 
a slightly smaller space than a T2X.  Craig told me that was because it 
doesn't have any "lumps" on the side....the casing is perfectly smoothe.

Here are the other specifications of usual interest--Wind Load : 25 sq. 
ft., Vertical Load: 900 lbs.
