[Elecraft] Fiberglass Mast Results

[K8bvj at aol.com]

I have been using the 33 foot fiberglass mast from MFJ for 3 yrs now and no 
problems here at my QTH......It's mounted up on the roof and supports my 
quarter wave 40 mtr vertical made of wire.  We have had winds of 70 mph and the mast 
was able to handle it quite well and it's self supporting  (no guys)  the top 
8 foot does whip with the wind but no big deal. You also need to use 
electrical tape at each section, so it doesnt colapse during wind movement.

Supporting a thin wire would be possible for an inverted L configuration but 
you need plenty slack in the horizontal length.

Tom :

I am using a Dk9SQ mast in a semi-permanent installation at home.
It is supporting a inverted-L W3EDP (end-fed 84ft wire) so there is
a 50+ foot horizontal component of the wire coming away from
the mast similar to what you are planning for the Battle Creek
special. It has only been up about a month so I can't comment
on how long you can expect the mast to last, exposed to the elements.
I do suggest that if you plan to buy one and leave it up for a
while that you should tape all of the joints with electrical tape after 
you
extend it to prevent collapse.

I have also looked at the MFJ version and it is a cheap imitation
in my opinion.

The DK9SQ masts are very well made and should provide many
years of service
