If noise is radiating from cables connected to an interfering electronic device like a computer monitor, you may be able to reduce the problem with clamp-on ferrite filters from Radio Shack. Dipole antennas are frequently used at around that frequency and thus termed half-wave dipole antennas. That's easy to do on 10 meters, but for 30 and 40 meters the Buddipole vertical with counterpoise is much simpler to use portable where you can't depend on tall enough dipole supports. Microwave Antenna Theory and Design. The V-beam antenna is the first part of a rhombic antenna.
