Antennas : 80M
  • 80m Shortened Dipole Antenna - This antenna just requires about 24m of free space instead of 41m that a normal half wave 80m antenna needs to hang up. The so called loaded dipole uses a coil in every dipole arm to electrically lengthen the mechanical too short dipole arms. Every coil has an inductivity of 120 microHenry.

Antennas : Active
  • PA0RDT MiniWhip - When experimenting with the WellGood Loop antenna, I came across the PA0RDT MiniWhip design referenced in several places. The construction of the PA0RDT MiniWhip is simpler than the WellGood Loop since there are no inductors to wind, but during my testing, I have found the loop to have slightly better performance.

Antennas : Baluns
  • Baluns and common mode chokes - Voltage baluns versus Current baluns. When to use them, differences, and typical usage in feeding antennas, or in resolving radio frequency interferences.

  • Build your own HF balun - A balun is a MUST for dipoles or similar antennas when they are feed with coaxial cable. From the RF point of view, the shield can be modeled as two conductors, the internal shield (the real shield, this is, ground) and the external shield, who is really far to be ground. In this way, your dipole has 3 arms, the two from the dipole and the coaxial cable shield (external face)

Antennas : Dipole
  • Short Monoband Dipole Antennas - KGD Antennas - The KGD antenna is an option for those with space restrictions. The idea behing this project is to provide a short dipole antenna for HF Bands and to allow operations on HF bands when its not possible to setup large antennas, using these short base loaded dipoles.

Antennas : J-Pole
  • J-pole antenna Calculator - Online calculator for J-Pole antennas. The J-pole antenna consists of a short and a long vertical pole with a feed point near the bottom. The antenna looks like the letter J, hence the name J-pole antenna.

  • Improving Gain of the Super J-Pole Antenna - The collinear J-Pole, often known as the Super-J, does improve the behavior over a regular J-Pole. there is an advantage when vertically combining 1/2 radiating sections to have a bit of separation between the half-wave end points. Get 0.8 dB more gain out of the trusty Super-J by replacing the traditional phasing stub with a long coil.

Antennas : Tuners
  • Semi-automatic antenna tuner project - Thsi article describes a microcontroller driven semi-automatic antenna tuner capable of handling power levels up to 150 watts. The device is a low pass filter tuner manually tuned by setting the optimized L/C combination by hand and then storing the values into the EEPROM of the mictrocontroller to recall them later (seperately for each band from 80 to 10 meters including WARC bands)

Antennas : VHF UHF
  • IAT Interactive Antenna Table - IAT is an excel sheet table evaluate parameters of VHF UHF antennas edited by Vladimir UR5EAZ. The difference between this tool and the existing VE7BQH Antenna Table is the use of G / T and C / N instead of the G / Ta parameter. In this table, Vladimir applies the ITU recommendations to assess the noise properties of a radio receiving system and shows the advantage of the G / T concept over the G / Ta concept when choosing an antenna.

Antennas : Vertical
  • Homebrew 5/8 Wave HF Vertical Antennas - The advantage of 5/8 wave antenna is that it has the lowest angle of radiation and has about 1dB more gain when compared to 1/4 and 1/2 verticals. So the 5/8 should be the favourite choice for DX.

Antennas : Wire
  • Lazy H Array Antenna for 40 meter - Make them simple then Make them work. The LAZY H antenna is a general type of antenna that is in the curtain array family. By placing two 1 wavelength dipoles in a plane that is at right angles to the direction of maximum radiation and keeping the proper in-phase current condition to each element, you can achieve a high gain bi-directional antenna.

Ham Radio : Demographics
  • Ham Census - What do amateur radio operators worldwide, think of their passion? What do we wish for? What are we frustrated about? How many of us are active, versus those that are taking a break? Do we have favorite radios, antennas, or even favorite cw paddles? Do we prefer one contest over another? The best way to find out is if we all participate in Ham Census. Join in and let all amateur radio operators know your thoughts "share your views" then you can find out what everyone else is thinking, in real time. Help shape the future of ham radio by participating in the world's most complete survey of amateur radio.
