[TowerTalk] wires in quad driven element

[Tom Horton]

Hector,
 I have been building and using quads for 40 years, and I have always
drilled the arms at the attachment points. I have never had an arm fail 
at the drill point, and they have been through some pretty hefty storms
and winds. One particuliar wind storm was 60 MPH  plus sustained for 
several days. Yes, the arms broke during that storm, but they broke at
the point where they were attached to the spiders. 
 I'm sure that some folks have had the arms break at the drill holes, but
in my case, that never happened.
 Another big plus is that it is much simplier and much less expensive!
Good luck!

I start building one of the 2 quads that will remplace my monobands 10-15-20m, i still thinking how to support in the spreaders the wires in the driven element , this one is the most inportant for me, i want to support the wires with out make holes in the spreader, increase electrical length with metal clamps or wires to attach in a strong way the wires , and can resist power around legal limit (most important) or more when the swr increase in the band limits or during a contest running power

i will apreciate an advice, followin this 4 parameters :
no holes in spreader , not metallic , hi power resistan and small weight. just for the driver or if this is practical i will add to all the other elements.
i was thinking in delrin insulators like the ones used in 2m yagis, but i have no idea how much power can handle , glued with resin to the driver .

tnx in advance
