The HFCM series conical monopole antennas are designed to propagate NVIS, medium or long distance communications and is characterized by low angle radiation patterns with their long term reliability and stability of electrical characteristics. HFCM series antennas are an excellent choice for omnidirectional HF communications where both ground wave and sky wave coverage are required. Due to its large diameter to height ratio the HF vertical conical monopole has excellent VSWR and omni-directional radiation pattern performance over specified frequency range. HF broadband vertical conical monopole antenna provides optimum performance over 4-30MHz band, eliminating the requirement of multiple antennas or an Antenna Tuning Unit, minimizing the cost and setup requirements. The antenna uses single aluminum tubular mast, supplied in sections for easy of shipping and handling which can be assembled in the field with simple hand tools, eliminating the requirement of bulky and heavy duty lattice mast.
The HFMP-230 multi polarized HF antenna is completely passive type which allow to receive 2 horizontal polarized and 1 vertical polarized electrical field signals simultaneously. The HFMP-230 HF broadband antenna is completely electrically isolated and all three dipoles are decoupled from each other making the antenna highly suitable for polarization-diversity reception. The vertical dipole is capable of receiving the ground waves at low frequencies and the HF field of the vertical ionospheric waves. Two horizontal crossed dipoles are capable to receive the horizontal components signals of all the azimuth directions. The vertical dipole is more adapted to receive ground waves and ionospheric waves coming from medium and long distance emissions. The 2 horizontal dipoles are adapted for the receiving of ionospheric waves coming from very short distance emissions, short and medium distance, ranging from the HF band 1.5 to 30 MHz. The HFMP-230 multi polarized antenna operates at D.C. ground with low resistance discharge path for protection against lightning and immunity to noise.
HF-LP series antennas are HF broadband log periodic type antennas. The HF-LP series HF log periodic dipole antenna uses 6063T6 ultra corrosion resistant architectural anodized aluminum alloy and designed to provide wideband directional transmission/reception of radio signals. The extra spacers are used between the support booms to improve mechanical durability of antenna. This log periodic dipole antenna system is particular suitable for transmission, reception, monitoring, scanning, signal intelligence, electronic warfare (EW) and jamming applications due to its broad band design feature. The HF log periodic antenna provides typical 7 dBi gain over 90% of the frequency band as the HF LPDA does not use loading technique to reduce the overall size of array hence provides the strong performance as compare to the loaded or active technique.
The HFBF-230 Horizontal Polarized Butterfly Broad Band Dipole Antenna offer optimum performance, fully automatic, low VSWR operation over the HF band 2.8-22 MHz and suitable for receiving, transmitting or HF spectrum monitoring or surveillance with polarization diversity. The antenna required two mast (lattice or tubular) having minimum 65 feet height (not in our scope of supply). The HFBF-230 broadband butterfly antenna propagates NVIS, local, medium or long distance communications. No Antenna Tuning Unit (ATU) is required for its operation. Antenna matching circuit BALUN is part of antenna. No active circuit is involved to design this antenna. The antenna is fully passive thus ensuring many years of maintenance free life. The HF Broad Band Butterfly Antenna provides optimum performance over complete HF band, eliminating the requirement of multiple antennas, minimizing the cost and setup requirements.
