Short Dipoles

DJ9RB details several antenna projects, including loaded dipoles and verticals specifically for the 160m, 80m, and 40m amateur radio bands. Featured designs include a 160m loaded dipole with end capacitance, a 160m loaded L-antenna, and a 160m kite-supported vertical. For 80m, the resource describes a short broadband dipole (80BBDP), an 8m high top-loaded vertical (TLV80) with elevated radials, and a shielded loop for 3.5 MHz.

For the 40m band, a 7m high top-loaded vertical (TLV40) and a 6m high portable top-loaded GP (TLV40mesh) are presented, both optimized for 7 MHz. Additional dipole designs cover 40m, 30m, 20m, 17m, and 6m bands, utilizing coaxial cable traps. The page also mentions specific vertical antenna variants like the TLV20 (GP14MHz) with two radials and the TLV30HWL-10MHz, a loaded half-wavelength vertical.

The content includes information on high-power homemade components, such as a 3.5 MHz AM transmitter from 1964 and a 14 MHz portable transceiver from 1977. It also touches upon measurement instruments, BNC connector assembly, and QTH details from DJ9RB's operations, including H44/DJ9RB from the Solomon Islands.
