DA- 4404  is a four-dipole elements array wide band UHF antenna for professional and amateur radio systems. Dipole incorporates 1/4 wave coax line matching circuit optimized for wide bandwidth and accurate matching. Maximum gain is achieved by coupling single dipoles into array. Dipoles in array are coupled by precision phasing cable harness keeping low SWR and minimum insertion losses. All connections made by soldering and are the one-piece.The vertical distance between centers of dipoles is 0.7  wave length. All antenna parts are made of aluminum . All components of dipole elements are DC grounded for better lighting and anti-static protection.  Frequency range:       MHz        380 – 480 Bandwidth SWR Gain, DBd:                                         9 Power rating, W:                             400 Overall dimensions, ft:              H 6.3 , W 1 Weight (approx.), kg:                       4.5 Impedance, Ohm:                             50  Termination:                              N- female Lightning protection:               DC Grounded    It is a serially manufactured antennas, it has high quality and reliability. Important: each antenna produced for each specific order and personal needed customer frequency range, so when you place the order, let me know your desired central (transmitting) frequency. The shipping time to US by regular shipping service is usually about 15 days. Also usually we need about 10 days to produce the antenna. Note: because of local customs, we not are sending any paper instructions by parcel! Short manual for installation: Install the supplied hardware exactly as shown in the photo. Colored markers on each dipole indicate upward direction. Accordingly, the drainage holes at the end of the antennas should point downward. all vibrators must be installed strictly on the same line and in the same plane below each other at an appropriate distance. To calculate the vertical distance in meters, between the centers of the dipoles, it is necessary to multiply the wavelength of the transmission frequency by 0.8. The wavelength can be calculated by dividing 300 by the frequency in MHz. The mast on which the antenna is installed must be no lower than the upper edge of the upper dipole. The antenna mast must be grounded. If you have any questions about the assembly and installation of the antenna, please contact me.

DA-2002  is a 2-dipole element array wide band VHF antenna for professional radio systems. Dipole incorporates 1/4 wave coax line matching circuit optimized for wide bandwidth and accurate matching. Maximum gain is achieved by coupling single dipoles into array. Dipoles in array are coupled by precision phasing cable harness keeping low SWR and minimum insertion losses. All connections made by soldering and are the one-piece. The horizontal radiation pattern is adjusted by changing the distance between dipole elements and supporting mast. The vertical distance between centers of dipoles is 0.6-0.8 wave length. All antenna parts are made of aluminum. All components of dipole elements are DC grounded for better lighting and anti-static protection.  Frequency range :            MHz    200 – 260 Bandwidth SWR Gain, DBd :                                       5.6 Power rating, W :                             300 Overall dimensions, ft :                H 5 , W 2 Weight ( approx .), kg :                       3.5 Impedance, Ohm :                             50  Termination :                                N- female Lightning protection :                DC Grounded  It is a serially manufactured antennas, it has high quality and reliability.

All dipoles must be installed strictly on the same line and in the same plane below each other at an appropriate distance. To calculate the vertical distance in meters, between the centers of the dipoles, it is necessary to multiply the wavelength of the transmission frequency by 0.625-0.8. The wavelength can be calculated by dividing 300 by the frequency in MHz. The mast on which the antenna is installed must be no lower than the upper edge of the upper dipole. The antenna mast must be grounded. If you have any questions about the assembly and installation of the antenna, please contact me.
