Two portable antennas for 6-meter
- VE7CA reprint an interesting article taken from arrl antenna compendium. Two elegant practical and portable 6-meter gain antennas, a two-element quad and a tree-element Yagi antenna for 50 Mhz-6 meter band
YLRADIO - Full wave delta loop
- This Delta Loop is a three-sided antenna suspended high in the air by vertical supports, such as tall evergreen trees. Recommended height is 40 feet or more at highest point, but higher is better.
80 m 3/4 wave LLV
- This is a vertically polarized Phased array. The left Vertical wire is 180 degrees out of phase
The full-wave loop antenna
- These omnidirectional antennas offer Horizontal polarization, and about 2.1 dbd of gain. They are much quieter than a dipole or a vertical, have a broader bandwidth and will usually out perform a dipole antenna.
An automatically tuned 7-30MHz mobile antenna
- This is a base-loaded vertical antenna that mounts on the car's roof. The loading coil is designed as a variable inductor, with a three-legged chariot that travels up and down inside the coil, with grooved brass wheels running on the coil turns, and driven by a slotted rotor tube.
- WSJT is a computer program for VHF/UHF communication dedicated to EME. Support FSK441 for meteor scatter, JT65: for EME and extreme troposcatter, JT6M: for meteor scatter (optimized for 50 MHz)EME Echo: for measuring your own echoes from the Moon, CW: for EME QSOs using 15 WPM Morse code
A 6M Transverter
- Build a transverter based on a 6M receive converter. A 32MHz TTL oscillator is used as the local oscillator for both transmitting and receiving. RX/TX switching is handled by three SPDT relays.
