[Elecraft] We need to develop the Ideal Antenna!

[Geoffrey Mackenzie-Kennedy]

Bob,

An interesting idea for a multiband centre-fed antenna was described by 
W4JRW in the December 1960 issue of QST, "Multiband Antennas using 
Decoupling Stubs".

The decoupling stubs that he used are not hung at right angles to the 
antenna wire, but are "horizontal" stubs which results in a tidy 
arrangement. In fact one of the antennas he described uses a length of 
tubular Twin-Lead, one conductor forming the antenna and the second 
conductor cut and removed in places to make the decoupling stubs, which 
results in a light weight antenna easy to carry.

73,
