The base K2 uses BNC. Generally though, all amateur antennas are compromises, and there is a lot of mythology on the subject. Other than that you really need at least a full halfwave at a reasonable height, everyone will have different idesa, and some people will try and sell you very compact antennas and claim they are as good. To take things to extremes, for a simple, halfwave, dipole aerial, you probably want superconducting wire, connected directly the antenna connector, with the radio suspended several thousand feet in the air, with wireless (possibly optical fibre) control of keying and return of audio. Obviously you will need to use batteries. Even replacing the superconducting wires with fat silver ones, that is unrealistic and may not be optimum for some propagation conditions. Your antenna will be dictated by how much you can afford, and where you can place it. (Even with the extreme case quoted, you might want a balun, and a free space dipole is more like 75 ohms than the 50 ohms design load.) -- David Woolley "The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio" List Guidelines <http://www.elecraft.com/elecraft_list_guidelines.htm> _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
