4 element 14 mhz yagi for 7 MHz
This article is about how to turn a CueDee 4-element monobander for 14 MHz into an efficient duo band for 7 and 14 MHz with some ingenious handles.
2 elementi Yagi per la banda 40
Mi son deciso di scrivere delle note tecniche e costruttive della 2 elementi Yagi per la banda 40 metri home made OB2-40
Linear Loaded 40m Dipole
Here is my dipole for 40m band. It is a simple linear loaded dipole feeded with 450-Ohm openwire feedline
40 meter Phased Array
Coaxial delay lines in his two-element phased array, and some users still use delay lines with good results

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
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
A simple SWR Meter is to be used at HF An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
