CD28/37/70 133-163MHZ VHF DIPOLE ANTENNA RFI RFI CD28-37-70

Utilising a patented matching circuit, the CD28-37-70 antennas are end fed dipole antennas combining a durable thermoplastic housing with a flexible tapered stainless whip section resistant to knocks and bends.

• Performance - Exhibits 3 dB improvement in performanceover a 1/4 wave whip
• Versatile - Ground independent design allows use in alternative mounting locations
• Rugged - The transformer circuit is housed within a high impact thermoplastic moulding which is virtually indestructible
• Unique termination method simplifies installation and re-cabling in the field
• Designed, manufactured and patented in Australia [Australian Patent # 596830 and 656793]
  
  (1) MopoleTM antennas such as the CD28 have been shown to exhibit a 3dB improvement in received signal level in the field when compared to a quarter wave whip however in pattern tests exhibit only 1.5 to 2dB over a quarter wave (equivalent to 1.5-2dBi).

This improvement in performance can be attributed to a lower radiation angle level of these ground independent antennas.
