MLAs are now being used not only in short-wave bands but also in VHF and UHF bands. If compared with a cheaper wire dipole, more demanding MLAs must offer an important advantage in operation, otherwise the growing number of happy users cannot be explained. The controversial success of MLAs is surprising as the new MLAs are quite costly commercial products on antenna market. We will try to explain the advantage and application preference for each model separately.

CB4M - the remote tuning control box for MLA

125.00 €

CB4M is an electronic unit designed to remotely tune magnetic loop antennas. Pulse-width modulation (PWM) is utilized to control rotation speed of a DC motor with a gear which drives the main tuning capacitor, the part of L-C circuit in a MLA. The microprocessor-controlled electronic unit was optimized specifically for the purpose of tuning the MLA. The process is sometimes named “spread tuning”.
