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
Trapped dipole for 40-80-160 meters
pop
- Build a space efficient trapped dipole antenna for 40-80-160 meter bands using RG-58 and PVC pipe by W8NX
Vertical antenna for 160 meter
- This high antenna require a large ground composed by 40 radials. It's not very handy expecially in windy situations but is very powerfull in pile-ups. In italian
Vertical half-wave aerials for 4m
- Practical designs pictures and alternative design of antennas for 70 Mhz by Ross Wilkinson G0WJR
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

- Introduction to NVIS advantages and disvantags.
About NVIS antennas
- What is NVIS Near Vertical Incident Skywave
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.
Balloon-supported verticals
- Using balloons to raise lengths of wire can be great fun - as well as making it possible to work the DX on 136 kHz from small gardens.
ZeroFive Antennas
- Vertical antennas for all HF bands, expecially 80 40 20 meters bands
Quantum Antennas
- 146/446 Mhz Dual Band, High Gain vertical Antenna
IPS - HF Systems MUF maps and prediction charts
- These pages provide general propagation advice for HF communicators. Information available includes inferred global propagation conditions, real time HF fadeout coverage charts, regional ionospheric vertical MUF maps and Hourly Area Prediction charts for Astralia and Asia, Europe and North America
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
Tower
- Windows program for analyzing vertical antennas. This program shows the resistance and reactance to be expected looking into a cylindrical metallic tower over a perfect ground. It gives a useful approximation of the values to be expected in a real-world situation.
