| The D2T 2-element
compact antenna covers 1.5 to 200MHz continuously 1kW PEP. Constructed with 2m
boom, 2x 6m elements and weighing 8.5kg. No ATU is needed, and only one feeder
of 50 Ohm coax is required. The whole assembly can be rotated by a lightweight
rotator. Adapted from a military design (the manufacturer¡¯s main business) the
dipole element is directly fed with coax cable via a balun, and the reflector is
fed through a phasing section and is terminated with an 820 Ohm
resistor. |

| The C-3 is 7 elements on an 18' boom with a single feedline: direct 50 ohm coax. All that is needed is a 1:1 balun or RF choke and you are on the air. Three monoband yagis for 20, 15 and 10 mtrs are the core of the antenna. The driver cell is a FORCE 12 multiband open sleeve, with the coax attached directly to the 20 meter element. The 15 and 10 mtr drivers are parasitically excited. All 7 elements in the antenna work together for great performance. The C-3 has gain on 17 and 12 mtrs without specific elements for these bands. A tuner is needed to match the VSWR on 17 and 12, as they are not matched to 50 ohms. The C-3 comes in a 4' box, ideal for DXpeditions. |
|
|
To enable having gain on all bands from 40 meters through 10 meters on a single boom, the C-3 has been enhanced with a 2 element 40 meter yagi using 37' elements to make the C-4XL. The front 40 meter element is the driver and it is placed within the reflector section of the C-3 (similar to the C-4 design). The boom is extended 12' for placement of the 40 reflector aft of the core C-3. The resulting 30' boom C-4XL antenna is the answer to covering all of these bands with a single boom. Two feedlines and baluns complete this great package. |
|
|
|
The WARC-7 is the world's first Yagi for the 30, 17 and 12 mtr WARC bands, featuring multi-monoband design and a single feedline. First used by K7K on the recent Kure Island DXpedition.

| The Carolina Beam 80
is part Carolina Windom and part Bobtail Curtain (sometimes called a ¡®half
square¡¯). It takes advantage of the best characteristics of both antennas. The
Carolina Beam has three vertical radiators directly interconnected by the single
horizontal radiator. It is this unique integration of horizontal and vertical
radiation components that accounts for the outstanding performance of this
antenna system. Another great advantage is its short length, only 30.4m (100ft)
long. |
|
|
| The Carolina Beam 40 has three vertical radiators properly spaced out to produce low-angle, beam like performance. The horizontal portion of the antenna interconnects the three vertical sections and acts as both a feed system and a radiating counterpoise. The result is a multi-element inverted-vertical antenna that operates high in the air, free of ground losses. It is a very efficient antenna. The overal length of the Carolina Beam 40 is only 15.25m (50ft.) easily placed in most small gardens. |
|
|
| Carolina Windom
160. The ideal all-band antenna that gives DX performance on the
low frequency bands. Optimum coax feeder length is 21.3m (70ft) or 50m (166ft)
(if using an internal ATU). Can also be used as an inverted V or a sloper. Gain
as high as 10dBd is achieved on some bands. 160m and 80m DX operators have
reported excellent results. The offset feeder often avoids the coax having to
drop down in the centre of the garden. If using as an inverted V, it is best to
support the antenna at the centre, leaving the vertical radiator in the
clear. |
|
|
| Carolina Windom
80. The size of this antenna makes it ideal for many gardens and
its DX potential will ad at least an S-point to your signal on most occasions.
The secret is in the vertical section which offers excellent low angle
radiation. But short-haul contacts will be boosted. As the antenna covers all
bands it can be used as the main system and it works equally well as inverted V
or sloper. The offset feed system makes the domestic installation that much more
convenient. |
|
|
| Carolina Windom
40. Covering six bands, yet only requiring 20.1m (66ft) of space,
this antenna is one of our most popular models. The vertical section offers
excellent low angle radiation and offers some useful DX opportunities for a
remarkably low outlay. If you use an internal ATU, it is recommended you feed
the antenna with 86ft of coax. If you have been using something like a G5RV you
will be really impressed with the improvement, particularly on 10m and 15m
bands. And remember, these are the bands that are likely to offers the best DX
as we progress into the new sunspot cycle. |
|

| Carolina Windom
20. With the new Carolina Windom 20 the size comes down to a very
easily accommodated 10.36m (34ft) and yet you get 5-band coverage. It has an
ideal radiation pattern and an unusually low angle of radiation, making a true
backyard DX antenna. The absence of traps and the 1.5kW power rating means you
have no chance of damaging the antenna, even with big linears. On all bands
above 20m it will leave the G5RV standing! Most internal ATUs will have no
trouble in matching this antenna. |
|
|
| Carolina Windom 160
Special. The 160m amateur radio band is enjoying a resurgence of
activity and the DX opportunities are better than ever before. But until now,
installing an efficient dipole meant having a lot of garden space. The carolina
Windom 160 Special halves the the space needed and at the same time offers a
superb all-band radiating system. The secret is in the Dedicated matching Unit
(DMU) which efficiently transfers power to the 160m quarter wave radiator. The
vertical section helps with both local and DX contacts. For correct operation
you will also need an external ATU as most in-built transceiver models will not
have the required capacity. |
|
|
| Carolina Windom 80
Special. Surely the answer to many hams antenna problem, a design
that fits into the average garden yet covers all the popular HF bands. Because
the radiator is only a quarter wave on 80m, your signal will be about 4dB down
on this band (less than 1 S-point), but as signals are generally strong on this
band, the difference is more than acceptable in order to fit the antenna in to
the limited space. On the other bands, 40m - 10m, you will enjoy full Carolina
Windom performance. Also note that with this model you will need an external ATU
as internal transceiver ATUs generally will not have the adjustment
capacity. |

| The SuperLoop 80 is a
high performance, full size, full wave, 80m loop antenna. On 40m it is a 2x wave
length open loop or Bi-Square. The stub in the top leg of the antenna opens the
loop when operating on 40m and selected other bands. This improves the antenna¡¯s
radiation pattern. Its gain is around 4dB, but it will seem a lot higher due to
its excellent, low angle, radiation pattern. The overall length of the SuperLoop
80 is 34m (112ft) with the HD ladder line switching stup 9m (30ft). The 50 Ohm
coax from the dedicated matching unit to transmatch is not critical but
recommended to be 1/2 wave length. Coax not supplied with
antenna. |
|
|
| The SuperLoop 40 uses
the same outstanding technology as the SuperLoop 80. This is a high performance,
full size, full wave, 40m loop antenna. On 20m it is a 2x wave length open loop
or Bi-Square. The stub in the top leg of the antenna opens the loop when
operating on 20m and selected other bands. This improves the antenna¡¯s radiation
pattern. In theory its gain is about 2dB on 40m and around 4dB on 20m, but it is
actually much higher due to the highly compressed low angle radiation pattern.
The dedicated matching unit, along with all the other components in the antenna
work together to provide a well-managed SWR on all bands. Coax not supplied with antenna. |

|
| The G3OJV 80-Plus-2
is a 3-band compact antenna covering 80m, 40m and 20m. It has a length of just
over 15.24m (50ft) but if erected as an inverted V or installed with its ends
dropped down, it could be accommodated in around 12m (40ft) of space. The design
uses low loss linear loading and can be operated without an ATU as the VSWR at
resonance is below 1.5:1. Input is SO-239 via a balun match. Power rating is
600W and the bandwidth at 2:1 VSWR is: 20m 350kHz, 40m 90kHz, 80m 80kHz. With an
internal ATU, operation is possible across most of 80m. On the two lower bands,
the resonant point can be adjusted when finally assembling the elements. Offered
in semi-kit form, you will need to make 4 solder connections, and attach the end
insulators. Assembly time is around 45 minutes. Final adjustment requires a VSWR
meter to achieve precise resonant points desired on 40m and 80m.

| The Highlander Mobile
Antenna covers all the amateur radio bands from 80 to 6m (including the WARC
bands). Max power rating 300W. It is constructed of tapered fibre glass rod,
with a copper winding covered in epoxy resin. Great attention has been given to
the antenna and it is totally weatherproof. The antenna is bandswitched by means
of taps along the helical wind. On 80m the entire 1.67m (5ft 6in) antenna is
used. For the other bands, the supplied connecting lead with banana plugs needs
to be used. Fine tuning is achieved by adjusting the short tuning rod at the top
of the antenna. The antenna is fitted with a standard 3/8in base for mounting
either on the vehicle or on a suitable mag-mount such as the
WMM-3401-38. |
