[TowerTalk] HF LOG-PERIODIC ANTENNAS Comments Please

[Pete Smith]

Having just repaired a couple of damaged elements in my top C-3E, I can 
testify that separating elements that have been up as much as 9 years is no 
problem if you used noalox, and drilling out rivets is no harder that 
removing a metal tapping screw or loosening a tubing clamp.  I have even 
added elements to these antennas (they used to be C-3s) in the air, using a 
cordless drill and TEK screws.

One thing F12 does that is annoying (but may be required by their taper 
schedules) is the use of elements that need swaged ends on individual 
tubing sections.  This effectively requires (most of) us to buy the 
replacement sections from F12.  I just bought two ~55" sections of 1/2 inch 
element tubing from them, and the cost was $36 plus shipping.  Seemed steep 
to me, and precludes quick fixes using aluminum on hand.
