Aerial Analyser Details edit / delete

In terms of features, pretty much a DIY MFJ-259 -- but built entirely out of common components, and including source code for the microcontroller.

Neat idea for an adjustable inductor: modify a wirewound pot.

Voltage Probe Antenna (VPA) Design 5 kHz to 500 MHz edit / delete

Very similar to the PA0RDT active antenna. I'm now not surprised that mine works so well for FM broadcast reception! This has an excellent discussion of the design.

ATV from G8AJN edit / delete

Notable for the bit on slot antennas. (The three-band J-pole-with-slots combo is pretty neat, although I'm not entirely sure I'd want it on the roof!)

Taking the Windom idea a bit further with traps. Neat, and good description.

Neat two-control ATU design. Making a better variable inductor (than I've currently got) would be the challenge -- note the wiper-on-toroid and variometer designs on this page... and also the air-cored coils at the bottom.
