These automatic tuners are suitable for coaxial cable or antennas endfed. The tuners are weather-resistant and suitable for outdoor usage. The max. 300, 600 or transmit power is 1500 W, depending on the model. All tuenrs antennas tune over the range shorttwave from 1.8 to 30MHz. Time to tune up is max. 15 seconds but usually starting from 5 seconds because the settings once found are stored in one of the 10000 permanent memories.

The MFJ works automatically, without manual tuning required. The tuning starts with a transmitting power from 2 Watts (MFJ004BRT, other models require 5W), but from 10 to 20 Watts are recommend for best results. The max power, while the tune should not exceed 20 Watts. Even if the tuner is equipped with resistant relay 16A/1000V, corruption may occur during optimization to higher powers. The network allows up to 192 tuners switched several L L and C values 192 different, resulting in an impedance matching range of 12-800 Ω with the MFJ-994BRT, and 12-1600 Ω with models 993BRT and MFJ-MFJ-998RT.


These models are housed in a weatherproof outer box. Power is supplied through the feed to that end a Bias-T coaxial MFJ-4117 is included in the shipment. All tuners are taken PL transceiver and the antenna, alternatively a post wire can be used for wire terminals fed. For wire antennas fed parallel external balun is required (not included).
