[Elecraft] Need advice on Small Tower

[Arthur Nienhouse]

Many years ago I replaced a TA 33 with a Force 12 C3,  I saw one db 
improvement in signals testing 15 meters and 20 meters ( before then 
after) with a station 30 miles away, it was even on 10 meters, in all 
ways of comparison it was better, I later put the 40 meter element on it 
which had its own feed line simply a great antenna is my report, which 
proved out chasing dx before then after how many tries how much power.

On a tower I would also check out the aluminum crank up getting the pro 
and con input from others a friend had one many years ago was happy with it.
If the antenna at low rest height is right you work on the antenna from 
the roof a benefit of putting it by the house.
