[Elecraft] Stealthy Antenna

[Mike Walkington]

All,

I'm planning to use a short piece of co-axial cable (6-7 feet) to get from
my K2 (with KAT2) through the wall of the house to an externally mounted 4:1
current balun (the W1CG model).  From the balun I plan to run twin feed
(20-30 feet) to a doublet or loop mounted under the eaves of my two storey
house (to avoid the anti-antenna covenants).  I have some questions about my
proposed configuration that I'd appreciate some advice on:

1) Can anyone offer some experienced advice on how long or short the co-ax
can be?
2) Is it OK to mount the balun in a plastic box?
3) Would you recommend a doublet or a loop?
