DA5000 - discone aerial for professional applications 700MHz ~ 3GHz
The DA5000 is a professionally constructed 'compact'
discone aerial for the upper UHF frequency range of
700MHz to 3GHz (3,000MHz). The top section comprises
of 16 horizontal elements and the lower section has eight
radials mounted on a solid stub terminated in a N-type
socket
.
The construction is largely of brass (BsBM) accounting for its weight of
700g, it is finished in a military grey colour. The overall length from the top
elements to the N-socket is about 240mm with the overall top diameter being
82mm and each radial 100mm long.
Termination is via a N-socket which is housed within the stub-mast to keep
adverse weather out. Use of quality 50 OHM coaxial cable is essential, at
least URM67 / RG213 for short lengths and even better quality for longer
cable runs.
Avoid touching the horizontal elements, improper handling of the
horizontal elements will degrade the aerial's performance. Due to the
exacting method of construction, it is not possible to replace components
which are mishandled and accidentally damaged by the customer.
The DA5000 is supplied with an aluminium stub-mast of 32mm diameter and
400mm in length, clamps to secure the aerial / stub-mast / support pole
(support pole not included), 'V' brackets are also included which accept a
support pole of 25mm - 50mm diameter.
