Antennas : 160M
160 Meter Antennas at W8JI
- 160-meter vertically polarized transmitting antennas center around this 200-foot tower
KE4UYP Linear loaded vertical antenna
- This is a vertically and horizontally polarized antenna the Linear loaded 1/4 wave length vertical radiator introduces very little loss for 80 or 160 meters
2-Element-Yagis for HF
updated
pop
- 2-Element parasitic Yagis for the Shortwave-Bands 10-12-15-17-20-30m. The antennas are feeded with the DK7ZB-match. A quarter-wave choke of coax is grounded at the socket.
Dual Band Vertical On Autopilot
- A good 20 & 40 meter dual band vertical using a novel tuning method that provides automatic band switching.
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
80m L Antenna. RSBEV's
- Reduced Size Broad Elevation Verticals
The Bazooka vertical
pop
- This is a deviation from the wonderful antenna the Double Bazooka.
Build a bazooka dipole
pop
- Build Your Own Bazooka Dipole: A VHF/UHF vertical dipole made from coax
HF Log Periodic antenna
- Plan for a log periodic antenna for the 14Mhz-30Mhz by F6DOP in french
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.
Multiband vertical antenna
- An article with pictures on a 80-10 mt vertical antenna with an Unbalanced-Unbalanced balun in italian
NVIS: Near Vertical Incidence Skywave
- Introduction to NVIS advantages and disvantags.
Vertical plane antennas' beaming comparision
- Animated quad and yagi comparison. You can see antennas' characteristics behavior in a vertical plane with changing of the height.
Radial systems and ground
- Radial systems for elevated and ground mounted vertical antennas by SteppIR
Antenna Gain versus Height
- Antenna gain for horizontal, vertical, and tilted orientation of a dipole for heights between 5 and 50 feet.
KC1XX Contest Station
- Amateur Radio Station owned by Matt Strelow.
The station is designed for competition in the multi-operator multi-transmitter category of high-frequency DX contests. Running with 7 towers 6 rotators, 8 beverage listening antennas, and 4 spotting verticals
Cross-Yagi antennas
- For two purposes a Cross-Yagi can be useful Satellite work or if you need both vertical and horizontal polarization for terrestrial contacts
6m Half wave vertical
- This antenna is very useful for receiving or scanning purposes, but you can use it for transmitting, too. It is 2,94m long and has a pi-configuration (Collins-Filter) for the matching.
ZeroFive Antennas
- Vertical antennas for all HF bands, expecially 80 40 20 meters bands
R7 Vertical Maintenance and Repair
- How repair the traps, and then homebrew the rest of the antenna, including the matching box
NEC4WIN
- NEC4WIN is a 32 bits commercial antenna simulation software based on MININEC3 developed by the Naval Ocean Systems Center in the 70s and 80s. It runs under Windows and can be used to simulate, analyze and optimize wire antennas, beams, verticals, etc.
NEC4WIN has limitations. They are the same as Mininec3 on which the engine is based.
Javascript antenna calculations
- Javascript online calculators for dipole 5/8 verticals with radials, and delta loop antennas
