This circuit is based around mixer/oscillator IC2. A 50mHz signal is fed to pin1 input of IC2 and mixed with the local oscillator injected at pin7. The resultant output is the antenna frequency minus...
This is the simple “Delta Loop” Antenna on the 40m band with low height of suspension. Its upper corner located at the height of λ/4. I.e. for this antenna acceptable any mast with height...

A dipole antenna is a symmetrical antenna, consisting of two quarter wave elements, connected to each of the two conductors (inner and outer) of a coaxial cable. You will need a center insulator for...
The Yagi antennas with a frame vibrator, located in the plane of the antenna, are called LFA-Yagi (Loop Feed Array Yagi) and are characterized by a greater operating frequency range than the usual Yagi....
Philips was founded in Eindhoven in the Netherlands in 1891 to meet the growing demand for light bulbs as a result of the commercialisation of electricity. In 1926 Philips introduced the miniwatt range of...
