Re: [Elecraft] Suggested antennas for the KX-2 for portable ops
Jack, A part of the answer to what constitutes a "good portable antenna" is going to depend on the supports available. BTW, this information pertains to any portable antenna choice, not just the KX2. It is all about what you are willing to 'tote' to your operating position and what 'sky-hooks' are available. If there are 'natural' supports available, and your KX2 has the internal tuner, the possibilities are large. Bruce Prior (one of the KX2 field testers who does SOTA) has found that a 58 foot radiator thrown into a tree and a 13 foot counterpoise laid along the ground is quite effective - used with a BNC to binding post adapter. End Fed Half Wave antennas can be effective, but some matching sections need to have some length of coax attached to act like a short counterpoise. If you are not backpacking, you can use a telescoping fiberglass pole for a support for those antennas. You will likely find a lot of specialized antenna systems that utilize loaded antenna elements - like the Buddipole system that can be erected in a variety of ways. In general, those are not as efficient as a full length wire. And lastly (for me) are the magnetic loop antennas (like the Alexloop) that can be easily set up, but must be tuned to the frequency of operation and once tuned, the bandwidth is quite small. Consider your desired operation and then make whatever compromises are suitable for that situation. 73, Don W3FPR On 8/12/2016 4:58 PM, Jack Colson wrote: I am sure that there are many ideas as to good antennas for the KX-2 in portable use.

Re: [Elecraft] Suggested antennas for the KX-2 for portable ops
KX3 portable I use the EF-40/20 from LNR. It would probably work on the KX2 also. ;) It was real easy to tune for 40 and 20 and has done a great job for me at Field Day, an NPOTA and out on my back deck. Very forgiving about the setup.
