[Elecraft] KX3 kit shipping estimate

[Geoffrey Mackenzie-Kennedy]

To add to Vic's comment, the connections between the tape and the feeder 
would have to be well protected against moisture and rain.  Any corrosion of 
these connections could result in BCI to nearby FM broadcast receivers - the 
rusty bolt effect.

A very neat and sturdy 6m yagi built by a friend many years ago for portable 
use, was made of fibreglass tubing.  Both the boom and each element support 
consisted IIRC of three lengths of tubing, with the outer parts "telescoped" 
into the middle part, and locked into place by a bolt, washer and  nut. 
Each element was made of large guage copper wire, taped to its support 
tubing.
