[Elecraft] Re: Mobile Antenna for KX1

[Larry Cahoon]

You can use the Hustler spider attachment and put up to three coils on the 
same antenna - I've seen it done with as many as five bands covered.

General rule is the higher you can get the coil the better. The down side 
is the higher the coil also put the weight up high and you may need to guy 
the antenna. I usually run two coils on one antenna (40 and 20) on major 
trips and always guy the antenna.
