We will try to
keep antennas for 20,20/40 and 40/80 meters on hand and ready
to ship quickly. What about other
bands? The new dual band designs are going faster than we ever
expected so there might be some delays at times.
Generally, if ordered by Tuesday it'll be in your hands by
the following weekend. What you get...
These antennas have twenty-two
or more
(depending on the frequency)
500
volt Silver Mica Capacitors and small
1'x1/2" circuit boards as
insulators making them strong
and able to handle a lot of wind and sun.
The wire is 'Silky' 14 AWG 19
stranded, tinned, with 40% copper-clad steel...basically the best antenna wire
we could find.
Each board has a center hole to work as a
mounting hole for those that mount it under the eaves of the QTH or
provide additional support along the antenna if
desired. Although there are a lot of CCD fans running legal limit
on their CCDs we still strongly suggest keeping them under
800 watts. We are asked often for antennas for other bands, like 10,
60, and 160 meters. We ran the numbers through the antenna modeler and tried
many combinations and even built a few test antennas. Bottom line - we could not come up with an antenna that
fit our standards for any bands but those we offer.
Our goal is to have something that will work on more than
one band if possible and fairly flat SWR across the band.
160 is to sharp, and 10 just has no advantages over a basic
dipole. CCDs don't work better in the form of a closed
loop. The model says there are no significant
advantages over a basic CCD. We do not make loop
versions of the CCD. This is not to say you can't
still put one up as an open loop. Just don't connect
the ends together. Long Wire configurations work fine.
Contact us first to see how long a special order would take,
but we have supplied them as a single complete wire with no
balun and with a tuner they work great. A good ground
is always important with this or any antenna system. Under the eaves is a common mounting when CC&Rs
are a problem. BUT, check for metal flashing that's
now a common construction technique around the edges of a
roof. And if there is metal rain gutters...well,
either one is an end game for any antenna around your house.
In the case of the metal gutters we suggest keeping the
power low, getting a good tuner, and use the gutters as your
antenna!! Make sure it's seamless or each section is
electrically bonded to the next.
If paying by check or money order make
it payable to "Presenceknown.com"
Complete with 4:1 Balun, end
insulators, and prepared wire w/cap modules. Ready for
coax and mounting, and putting on the air!!
Postage is paid on all
US domestic orders!!
*International orders will
require additional postage. Experience shows an additional $25US will
handle most countries,
but in each case we can quote the additional amount before or after order,
just contact us! Note: Although we use Paypal, you
do NOT have to be a member to place an order via credit
card. We also accept checks or money order at the
address to the left. Credit card orders will show the company name
of Presenceknown.com, LLP And if you would rather talk to a person on the phone and order one,
feel free!! Dave @ 480-510-1721 |
