Test EH antenna for 630 mt band &CW Beacon EA1HBX
Aquí tenemos la construcción de una antena EH "aceitunera" que monté con recicles de latas de aceitunas donadas por el colega Javi EB1HBK.
Consta de dos cilindros capacitivos con dos latas de gran dimensión sobre tubo de PVC 100 MM * 1500 mm, dos bobinas de defasaje alimentando estos cilindros a 0 y 180º, una de sintonía con condensador variable paralelo, y un choke de adaptación galvánico, acoplado a 1,0:1 de Roe en la banda.
En la parte emisora, un pequeño generador con un software de CW transmitiendo atacando la antena.En el Rx, una antena Lc resonator en el equipo Yaesu ft 817.
Here is the construction of EH antenna called "aceitunera" I made with olives recicles cans donated by Javi EB1HBK colleague.
It consists of two cylinders with two cans capacitive great dimensión mounted in a pvc tube of 100 * 1500 mm, two coils of dephasing feeding these cylinders to 0 and 180º , a variable capacitor tuning with parallel and adaptive choke galvanic Roe 1.0:1 coupled to the band.
At the Tx station, a small generator with a CW transmitting software antena.
In Rx, an 630 mt- Lc resonator antenna over Yaesu ft 817.
