[TowerTalk] 160 Inverted L Question

[Mike Ryan]

    Some years ago I ran across an article about someone using a COKE / pop
bottle as the base insulator for a 160 vertical. Others may have
other/better ideas. A friend is going to try to use roughly 40ft of metal
tubing vertical and wants to insulate from ground the vertical component
then run the remaining length of wire horizontal. ARRL Antenna books have
some ideas but did not see any with the thought of insulating the base in
mind.  Ideas ?   - Mike
