[Elecraft] Attic Antenna Tradeoff?

Greg,

Add me to the Attic Ant "user group". Mine is a multiband doublet,
details at:

 http://www.radioactivehams.com/~n0rc/antennas/

I've worked stations all around the world, and place well in QRP
contests/sprints I sometimes enter, usually top ten or 20. I really
can't give you a good measure for outdoor verses indoor ant my QTH,
never had an outdoor antenna up long enough to make meaningful
measurements. I can say that it works better than no antenna, and given
CCRs (Concentration Camp Rules ;-) no outside antennas, that is saying
something, I guess.

Some advice I will pass along: Have your attic insulated with "Batt"
type material, not the spray-in stuff. Walking around/working in a attic
full of spray-in stuff is miserable. Also, consider adding 1 or more
2-3" DIA plastic conduits for cable runs, and maybe add some "catwalks"
in the attic to facilitate moving around.

GL,

73, Rod N0RC
