Power and SWR Meter
This update replaces the teensy ++ 2.0 microcontroller with the much more powerful teensy 3.2 32 bit arm cortex-m4 running at 96 mhz

USB/Serial SWR Meter
This project is mainly about software. For computing hardware, I will start with the Arduino UNO R3, and much of the work will be done in its firmware
Tuning Your Antenna
This handy device can give you a lot of information about an antenna. It can tell you if it's too long or too short. It can tell you an antenna's resonant frequency
The Resistive SWR Bridge
The resistive SWR bridge is highly recommended for both beginners and experienced constructors

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
