[Elecraft] [KX3] OT: NVIS with KX3

[george fritkin via Elecraft]

Since you are going to operate only one band, why not a resonate dipole.   40 meters should be ok and the antenna is only 66 feet long.   The added benefit is no antenna tuner needed.   You will find shortened antennas like the Buddipole are not that efficient.  I would suggest that before the trip, try a couple of different configurations locally with your friends using 40 meters as a test,

Hi Johnny,

On 40 meters, I work all over the West Coast (0-1000 miles north/south) during the daytime with 5 to 10 W. The antenna is a random-length OCF dipole about 15' off the ground. I'm not sure how many clouds I'm burning, but many of the stations I work are short- and medium-range. I think this should work in your situation.
