As with most of my hobbies, I usually need to have at least one major project
going on in each area of interest. Since I have now completed the acquisition of
an assortment of basic kites, it is time to look for a project for the following year.
To this end, I am presently considering a project that will combine kites with the
technology and components from my radio controlled model airplane and
amateur radio hobbies.

KITE PROJECT FEATURES BEING CONSIDERED
In the mean time, as I am developing the various elements for my giant bird kite
project, I am working on the addition of an amateur radio antenna to my 12 foot
ITW Rivera Highlander delta kite which is sufficiently large to successfully
transport a full size 20 meter dipole amateur
radio antenna hundreds of feet into the air.
The antenna that it carries can also be easily
tuned to 20, 17, 15, 12, 10 or 6 meters
depending on the band that is open at the
time. A length of small diameter, light weight
RG-8x coaxial cable is used to connect the
transceiver on the ground to the antenna
carried by the kite. The kite's antenna can be
powered from the ground using either my 100
watt bicycle mobile or 500 watt van mobile.
When the van is parked on the beach and the kite is flown out over salt water,
the radiation angle will be significantly lowered so that this kite antenna will
provide truly outstanding performance.

9. Amateur radio antenna
This photo shows my white Ghost Delta kite which has been adapted to carry a
pair of 36 inch tall inflatable aliens. A harness made of two inch wide white Velcro
straps has been sewn onto the kite's sail in order to hold the passengers in place
during the flight. When not being used to carry passengers, these straps are
attached flush with the sail so they are not visible and do not create unwanted
drag. With passengers in place, the kite needs a 6 mph wind to fly due to the
increased weight and drag.
This was our kite portable operating position with Bob (W6SDO) at the mike.
The picture was taken by co-operator Dave (WB6SQA). The Icom IC-7000
transceiver powered by 20AH of self contained lithium batteries is housed in the
brown box sitting on the milk crate and was borrowed from my bicycle mobile.
Our power output ranged from 60 to 100 watts as the height of the kite varied.
The blue handled stake grounded any static voltage that might otherwise build
up on the antenna. The blue garden wagon contains a lead brick which makes it
a suitable anchor for the kites 200 pound rated fly line as well as the RG 8x
which feeds the power to the kite (and also serves as a backup catch line if the
main fly line should fail). The modified hose reel is used to store the 150 foot
long coax feed line and the white tube behind the wagon is used to store and
transport the kite.
Together, Dave and I made 23 contacts which included 9 states plus two
Canadian provinces. Our signal reports ranged form S7 to S9+20 which sounds
about right since our output power and antenna height was in the same range as
the majority of stations that we contacted. Our next official kite mobile operation
is scheduled for the Memorial day weekend when we will be operating using the
Special Event call sign K6K.
Please come back and visit from time to time as more
projects are added to this page. Happy kite flying!
