[TowerTalk] Dipole Center Insulator

[Joe Subich, W4TV]

I don't care for the Budwig with it's heavy rod connections.  I found
it difficult to get reliable connections to the legs of the antenna
that don't break.  My recent wires have used the Jetstream center
insulators from R and L Electronics:

They're fairly robust and I suspect would even take the stress of being
strung between a couple tall trees (although my wires are all hung as
inverted Vs).

73,
