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
