Stacking Transformation
The ideal impedance transformation ratio are actualy ZL = 50 Ohm and ZI = 100 Ohm, but to get this ideal impedance transformation means that for TR, we must use a coaxial cabel with a Characteristic impedance Zo = 70.71 Ohm

Super facil antena vhf 1/4 onda
Antenna Ground plane (GP) has the property of receiving and transmitting in an omnidirectional way, that is to say everywhere equally

Super J-Pole Collinear
The antenna J is very simple in construction and has good results

In the second part of this article you will find images of the antenna and how I built it

T-match for vhf -uhf Antennas
The T-Match with its balanced feed point is one method of feeding a Balanced Dipole
