The HF-2-30 HF Broad Band Folded Dipole Antenna offer optimum performance, fully automatic, low SWR operation over the entire HF band 1.5 – 30 MHz. without need for an antenna tuner. The HF broadband dipole antenna will propagate NVIS, local, medium or long distance. HF-2-30 is a two folded dipole antenna whereas HFM-230 is a multi-wire 3 wire broadband dipole antenna. The efficiency of HFM-230 multi-wire broadband dipole antenna is much higher as compare to HF-2-30 folded dipole antenna. Both broadband dipole antennas can be mounted either in an inverted “V” using a single mast, or in a standard dipole configuration (Horizontal Polarized) using two masts. Also both Dipole Antenna provides optimum performance over complete HF band, eliminating the requirement of multiple antennas or an Antenna Tuning Unit, minimizing the cost and setup requirements.
The HFV series antennas are designed for HF vehicular mount application. The HF vehicle mount antenna is made of ultra corrosion resistant marine grade stainless steel whip encapsulated in fiberglass sleeve, designed to be used with an Automatic Antenna Tuner (not supplied with the antenna). The overall length of HF vehicular mount whip mobile antenna consisting of multiple sections. A M10 stainless steel stud (as a termination) is fixed at the lower section of radiator which is insulated from the mounting fixture/flange. The HF vehicle mount antenna base section is equipped with heavy duty stainless steel bi-conical spring coil to absorb shocks fitted with standard NATO four holes pattern. The HF whip antenna base is supplied with black powder coating and stainless steel whip is supplied with NATO green powder coating. This HF Whip Mobile Antenna supplied in dismantle condition for easy of shipping and handling and can be assembled in the field with simple hand tools. The HF vehicular mount whip antenna elements are tapered and threads are provided at each element making the antenna assembly a simple job. The antenna is supplied with eyes protecting cap fitted at the tip of the whip.
The HFTD series antennas are designed for military HF tactical communication application. The HF Tactical Dipole Antennas offer optimum performance, low SWR operation at the resonance frequency and suitable for 100 & 400 watts RF Transceiver. The HF tactical dipole antenna has exceptional strength and durability by utilizing marine grade stainless steel stranded rope/wire radiating elements materials. The HF tactical dipole antenna propagates NVIS, local, medium or long distance communications system since its deployment can be controlled by operator himself to suit all operational requirements. The HFTD Series HF tactical dipole antenna can be configured for multirole such as a Horizontal Dipole configuration is suitable for short or medium range omni-directional coverage and long distance communication at Broadside of antenna; Sloping Dipole configuration is suitable for short or medium range omni-directional coverage; a Bent Dipole or Inverted L configuration is suitable for low frequency ground wave communication; a Base Feed Vertical configuration is suitable for omni-directional ground wave and long distance sky wave communication; a Sloping V configuration is suitable for directional medium range communication; a Inverted V configuration is suitable for directional long range communication. Any one of configuration can be rapidly deployed from carry bag by an operator within 10 minutes. The HF tactical dipole antenna elements are calibrated with heat shrink printed markers in 0.5MHz interval between 3 to 10 MHz and 1MHz interval between 10 to 30MHz band. The antenna is supplied with halyard/throwing rope, stainless steel “S” hooks, Balun/junction box fitted with chromium plated brass terminal, winding spools, throwing weight, carry bag and 10 meters long low loss feeder cable fitted with connectors.
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.
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.
