Travel Antenna Details
This is a low cost homebrew two band travel antenna for 20 and 40 meters. It is based on the B&W Travel Antenna concept with a telescoping whip and a loading coil

Most amateurs have become used to tuning for a minimum indicated SWR. This is meaningless in a mobile installation. WHY? An efficient mobile whip is unlikely to be 50 ohms
Making a 28MHz rubber duck for the FT817
The main component in this design is the supporting rod, which the wire is wound upon.The rod needs to be 530mm for the antenna, plus about 15mm, which is inserted into a PL259 for RG8 style coaxial cable

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
