Johan, SM6LKM, said:
A long thin wire tied to a cluster of helium filled Durex units will
dramatically increase the effective height of the transmitting antenna!
I didn't find these type of balloons very successful and a helium filled
Durex would only lift its own weight. Furthermore the helium leaked out of
them fairly quickly.
These experiments confirmed the neighbours worst fears about the character
living at number 37.
Balloons need to be at least 1m in diameter and made of mylar to be of any
use for supporting antennas.
As I understand it 'Shoestring' has come to mean a bargain or low cost. The
meaning of 'cheap' is changing from 'low cost' to 'poor quality'
