Spyderbeam antenna per gli 11 metri

Antenna CB 27 MHz Links

HB9CV 2 elem. 27.000 mhz
The HB9CV antenna or Swiss antenna is a fully fed antenna with two elements in the form of two unequal length dipoles

HB9CV 2 element yagi for 11 meter
The idea is to get an small antenna, this is a great solution. The HB9CV antenna is smaler than a 3el. conventional Yagi but you get the same gain and caracteristics

How does a CB radio antenna work?
CB portion of the spectrum begins at 25.01 megahertz, so a full wavelength antenna would be a bit more than 39.34 feet long

How to build a SWR meter for 27 mhz
The transformer is made of 3 copper lines on a PCB, each of them 65mm long


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

Rx antennas 4Square Rx Vertical Array

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

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
