Antena Cubica Multibanda


This is the quad-cubic antenna for 2 elements. 14.25 MHz = 21 Mts 50 cm, 21.30 MHz = 14 Mts 38 cm, 28.60 MHz = 10 Mts 73 cm

A Homebrew Quad 3 bandes 14-21-28
All elements of the rod and arm are made of fiberglass. The idea is to rebuild this 5-band antenna

Build a Multiple-Polarization Quad
The feedline is connected to point A, which gives a horizontally polarized transmitted signal

Double Quad 13CM 23 CM
Here is a description of a 9 dBd double quad and its calculations


Linear-loaded-short-dipole-21mhz

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
