6 band windom antenna 80-40-20-17-12-10m
Our antenna will serve us for a long time if we isolate these parts from the external environment with hot silicone or similar materials after soldering the connections in honey. We can use our antenna in all hf bands except 160m, 30m and 15m

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

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
Interface-for-digital-broadcasts-with-integrated-audio 4-port HUB, with a TUSB2046. With port 1 of the HUB we drive the FT232RL; with port 2 the PCM2904, furthermore, we decided to leave ports 3 and 4 free
