• 50 Ohm Coaxial Dipole - This dipole is composed by a coaxial structure and non-folded dipole made from two open conductive cylinders, and benefits from the stub compensation of a folded dipole by passing an insulated wire through the axis and connecting it to the ends of both limbs. By G4CQM

• Coax Stubs for 20m and 40m - When operating contest in a multi transceiver environment interferences between the 40m and 20m are guaranteed. An easy and inexpensive way to reduce interferences is to add coax stub filters

• Coax Notch Traps - Attenuating adjacent bands - Targeted Attenuation for Adjacent Bands. Filtering is needed between the two rigs to prevent physical damage to the RX front end and to prevent the kinds of high-signal overload conditions like desense and IMD - as well as containing harmonic energy.

• Cheap antenna to make from 160m - 6m  ^pop - The antenna is nothing more than a simple 2.4 metre square loop drawing pinned to the internal brick wall of the spare bedroom. Yep, thats right, the inside wall of the spare bedroom - ideal for flat dwellers, hotel rooms or whinging neighbours, The loop has a simple switched inductance at the top of the square loop and uses a simple coaxial stub to tune the antenna. An additional variable capacitor placed across the feedpoint can be used to fine tune the resonance of the antenna, by Andy G0FTD
