Building The Lazy H Antenna
The Lazy H is probably the most elementary form of curtain antennas. The lazy-H usually consists of two horizontally polarized doublet or dipole elements, although with some loss in earth reflection gain it can be oriented vertically as an "H"
Broadband Antennas
The advantages of a broadband antenna are obvi-ous—fewer adjustments during tune-up. For some of the new broadband transceivers andamplifiers, a broadband antenna means no tune-up at all
Carolina Windom antenna
Here is my home HF antenna. It is an off centre fed dipole, with 10 feet of vertical radiator. It needs no tuner on 40m, 20m and 10m
Cobwebb 10-12-15-17-20 meter Building The Antenna
This antenna, I made, not only covers 10-20m but tunes quite well to 40 and 80, has a reasonable swr at 6m! and a good swr from 120Mhz to over 150 Mhz
Diamond w8010 banden 80-40-20-15 en 10 meter
The antenna described here is known by different names. It is a combination of two dipoles that are shortened with coils and thus cover the tires 80-40-20-15 and 10 meters and yet still have a fairly small size

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
