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 15 days to produce the antenna.
Note: because of local
customs, we not are sending any paper instructions by parcel!
Important !
Due to russia's invasion of Ukraine, we are now at war and are limited in production capacity and do not powder coat the antennas yet, so they will have a natural aluminum color and will not be painted.
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 0.625-0.8.
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.
