Antennas for HF mobile operation  ^pop - The following description should give you guidance on how to build a mobile antenna for HF bands yourself, using a very cheap CB-mobile whip antenna base. Antennas for mobile operation 7Mhz ,10Mhz, 14Mhz, 18Mhz, 21Mhz, 24Mhz,28-430Mhz

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

VLF-LF And the Loop Aerial - The article discusses the theory of loop aerials for receiving and how they reduce the level of local noise. A Loop Aerial is described suitable for use on the LF and VLF bands together with a circuit of an interface loop tuner and preamplifier. The discussion extends to the problems of amplifier noise and the advantages of tuning the loop.

Radio Free London - Radio Free London is now BACK ON THE AIR. We are now back on medium wave (AM) on 1125kHz (266 metres) and 5805kHz short wave every Sunday. The SW service consists of a 4 hour loop of 2 programmes. The medium wave service has a third bonus programme making it a 6 hour loop of 3 programmes.

Grounding Concepts - What is ground?RF ground and the ground plane, how can I tell if I have a good ground? ground loops

Why grounding - Overvoltage protection, Voltage stabilization, Grounding in wiring, Ground wire resistance

Antenna Noise and Signal Cancelling at LF - By using the signals from two antennas, controlling their relative amplitudes and controlling the phase of one of them, unwanted signal or unwanted noise can be phased out. Circuitry is described which uses the signal from a wire antenna to provide selective cancelling against the signal output from an LF loop antenna.
