Flags and Pennants - Excellent low-noise receive antennas originated by EA3VY and optimized for 160 meters by K6SE

Crossed-Wire HF Antenna - This Crossed-Wire Electrically-Steerable HF Antenna, capable of transmitting signals over the entire 1.8 to 30MHz HF range, and capable of receiving signals at much lower frequencies is basically a crossed centre-fed wire system, consisting of four thin wires brought to a central mast by G3YNH

160/80m Coaxial Receiving Loop Antennas  ^pop - Receiving loop antenna for top band. This antenna allow to reduce noise on both bands. The stand alone 80m loop is approximately four feet in diameter. And made of light weight material. Which makes it ideal for portable use or you can mount it above a pre-existing vhf antenna, and due to it's small size it is quite rotatable.

Low Noise Antenna Connection - Reducing noise to your antenna can gain your aerial performance, learn how.

Radio Components - The widest range of stocked components for the electronics, electrical and mechanical engineer.

Scanrec Scanner Recorder - Scanner Recorder (Scanrec) is a free audio recorder that is primarily designed to record speech. It has a VOX control that allows the user to save disk space when no sound is present in the signal. Since FM communications has such an effective squelch, the recorder works best with FM. HF ham bands and World Band radio have such a poor signal to noise ratio that the VOX gate on Scanrec might not be very easy to set.

Electronics Toolkit - Solve electrical and electronics equations quickly and easily with the Electronics Toolkit

TCalc - TCalc+ analyses the Noise and intermodulation performance of radio receiver front-ends.
