TEKBOX TBMA2 Antena dwustożkowa 30 MHz– 300 MHz

Product Overview

The TBMA2 is a dual cone measurement antenna for testing radiated EMC emissions and generating defined field strength. With its affordable price, it is an excellent choice for any laboratory performing EMI pre-testing

It features a frequency range of 30 MHz to 300 MHz and has directional characteristics similar to a dipole antenna.

The TBMA2 is supplied with a ¼ " threaded POM mount for mounting the antenna on standard tripods.

The TBMA2's radiating elements are made of stainless steel components to avoid the disadvantages of contact degeneration over time that are associated with unwelded structures using aluminum. The radiating elements are not welded, but are attached with lag screws, which makes assembly and disassembly easy and the antenna easy to store and transport.

The antenna elements are powered by a 1:4 balun with a power output of 100 watts.
