SPECIAL PURCHASE! Grove Enterprises has bought the remaining new inventory
of the popular
AOR DA3000 discone VHF/UHF antenna and can offer you the best
pricing on the market!
Covering 25-2000 MHz, this 16 element scanner antenna comes with 50 feet of
low-loss coax and a BNC connector.
Originally selling for $139.00, we can offer
you this fine antenna for only $119.95!
Or for a greater savings buy two for the
low price of only $104.95 each.The DA3000 is a 16 element ‘receive’
wide band discone aerial providing a useable frequency coverage from
25MHz to 2GHz. Many of the 16 elements are of different lengths ensuring true
wide band characteristics including
one ‘loaded’ element to enhance the low frequency performance. This aerial is
designed and manufactured
in Japan to exacting standards. The DA3000 is supplied with 15m of quality
RG58/U coaxial cable terminated in a
BNC plug for the radio connection and a TNC plug in the aerial base. Clamps are
also provided to fasten to a
suitable pole up to 52mm.
What is a discone:
For wide coverage in the VHF-UHF bands a compromise has to be met and the most
popular aerial is a discone (a disk of
elements over a cone of elements). Their appearance is like a large spider or
umbrella without the covering material, the
better models have about 16 elements... avoid discones with only a few elements
(such as six). Typical usable coverage
starts from about 25 MHz and extends continuously to 500 MHz, 1300 MHz or even
2000 MHz. The coverage peaks
and dips throughout it’s range as the elements interact to provide the widest
possible coverage. Due to their
necessary construction discone aerials are a little prone to “wind noise” &
possible damage in severe gales.

DA3000 discone antenna assembling
1. Screw two “A” elements diagonally with washers in upper screw
holes of main unit.
2. Screw two “B” and four “E” elements (threaded) diagonally with
washers in upper screw holes. (A-A vertical to B-B, E-E vertically
another E-E)
3. Select two ‘no mark’ elements with threaded head and joint them
with two “C” elements to be the longest elements. Insert two
combined “C” elements to slant hole of main unit just below “A”
elements and tighten set screws by wrench included.
4. Insert and tighten two “D” elements similarly just below “B”
elements.
5. Insert and tighten four “E” elements (non threaded) below each
“E” elements (threaded) of above 2.
6. Attach two mast mounting brackets to aluminum pipe with
proper spacing of approx. 300mm.
7. Feed coaxial cable “TNC” plug side through aluminum pipe and
connect the plug to the main unit.
8. Insert the main unit into aluminum pipe and tighten a screw.
9. Install whole unit to suitable mast (not supplied) by “U” shape
