 Build a 12/17 Meter Trap Dipole by AD5X
Why a 12/17 meter rotatable dipole? Well, many folks have verticals for the lower bands, and multi-band dipoles or beams for 20-, 15-, and 10 meters. But often you don’t have an antenna for the 17- and 12-meter bands.

 Rotary Dipole for 12/17 Mt by IK4DCS
After all the experiments on the WARC bands self-made antennas I had just to try with a coax-cable-trapped rotating dipole.

 Use a 28MHz antenna at 24.9MHz by JA1HWO
The quarter wavelength of the 12m band is 3m, so if you use a 10m band antenna, just add 0.5m (3-2.5). Even if the antenna is already shortened and the length is not 2.5m, the idea is the same.
