MARUWA’s multifilar antennas offer a broader angle of reception than patch antennas. This enables the antenna to track more satellites signals even when the device is tilted from the upright angle of use. The dielectric core together with the fly-wheeling effect of the advanced decafilar helical design provide excellent beamwidth and low elevation gain, which is maintained in relatively cluttered use scenarios. The MHF-1621A/B acts as its own filter, attenuating signals from common cellular and ISM frequencies by as much as 30dB.
