Cubical Quad Antenna Designpop
- By N6VNG, can be used to determine the element lengths and the gamma match values for different frequencies, includes link to excel files with formulas to dimension your quad antenna.
- Base station and repeater antennas, mobile antennas, ,multi-band HF antennas , handheld transceivers, receiving and scanner antennas, power meters, swr meters, power supplies, coaxial switches
- Freeware antenna software that lets you see what the polar diagram of your rotatable beam actually looks like where it is operating.
With PolarPlot you can measure the polar diagram of the antenna and check for abnormalities - compare plots taken before and after changes to the design or location - check the -3dB beamwidth - look at the front to back ratio - see the size and position of the sidelobes.
- Program designed to do spectral analysis and real-time audio filtering on reception of audio signals for EME, VLF, SETI applications. Offer support for MTHELL, QRSS, DFCW, NDB, WSJT by I2PHD
