New for 2013 - The DES-Dipole rotating dipole from InnovAntennas
NEW for 2013, the DES-Dipole. A multi-band rotating dipole with no
traps, no coils, no matching devices in fact, No Power-Sapping
'heater' devices at all!
This means maximum radiating efficiency. In other words, most of your
power is transmitted rather then being lost somewhere.
DIRECT FEED, 50 Ohm !!
There is a single feed point on this antenna, the other bands (the one
in the picture covers 15m, 10m and 6m) are parasitic elements. A
Standard dipole is normally around 70Ohm and gives 1.4:1(ish) SWR. All
three elements on the DES-Dipole (so called due to the OP-DES yagi
style elements on the upper bands) compliment each other and ensure a
low, flat SWR on each band.
NO POWER LIMIT!
Yes, you can pretty much put into it what you like. So why do antennas
have power limits? When matching devices, coils or traps are
installed, inefficiencies can creep in. This causes heat. the more
power, the hotter they get until.. well, you know the rest! 5KW? No
problem!
SUPER STACKING
Stacking 2 or more of these gives excellent performance with GAIN.
COMPACT DESIGN
Due to the deployment of the bent downward elements, the area this
antenna covers is no larger than that of a 10m rotating dipole.
WHY WAIT?
Register your interest now, mono, dual and triband versions are
available as of January. Email sales 'at' innovantennas.com for more
information!!
