spiderman 4 element for 27 MHz

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

Atu balanced feeder antenna system

Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
