[TowerTalk] Alpha-spid

["Howard Klein" <howk2@hotmail.com>]

Bruce,
The picture of my installation can be seen on the link noted by Don below. I 
have both instances of the Alfa Spid that Don mentions; one in the tower an 
another on a swing arm extended out. Both work very well.

Well, from the US Tower website it says: Snip
Depending what you want to put on top, another alternative to is to mount 
the rotor outside the tower. The rotor itself is very well suited to taking 
this kind of side load. It will mount directly to a stub pipe up to just 
over 2.5" diameter so no lower mast adapter is needed. For testing this 
fact, I have had a 6 element 20m monobander 48 foot boom on an AlfaSpid 
mounted outside the tower for just about 1 year. The wind actually destroyed 
the yagi last fall but the rotor was fine. The yagi has been rebuilt (my 
trussing slipped and precipitated the failure) and both have survived the 
winter and summer and the test is ongoing. Looking at it during wind gusts, 
I don't feel this load is stressing it very much, but it is hard to put a 
number on just what is too much, until something fails. Some pictures of 
other users, and some mounted outside the tower can be found at 
http://alfaradio.ca/inuse.html (the other pix link seems not to work at the 
moment)

Hello:

Will the Alpha Spid fit into the top section of a HDX-555?
