[TowerTalk] 10 meter antenna

[Renegade]

Hi ya'all - as I have the Antenna Handbook dated 1976, there must've
been some changes since.  I'm looking for the velocity for RG213U.

I'm also looking for the formula for a 5 el parasitic array length and
element spacing if they still use, e.g.
Reflector:  Length (ft) = 500 ÷ ƒ (mhz).

Last question (for now) is what do people use today to coat (or not) the

elements that slip into each other and boom connections?  WD40,
Silicone, etc., or nothing?  Comments please!
