The Box-Delta Kite at 200 feet
Click picture to return
The latest project is kite aerials. Having spoken to Jon (G2FHF) who fly’s kites
quite often, mainly for top band operations, I have decided to give it ago myself.
First place (as usual) is a troll of the internet for information. The main problem for kite antennas appears to be the static build up. With this in mind I tried a auto-transformer (that is just a coil of wire) which one side is grounded and the other is attached to the wire. Tuning is achieved by tapping on to the coil from the radio to have a feed impedance of 50 ohms. First try was a complete disaster and thus returned home for a rethink.
Out for the second time with greater sucess. I stayed on 3.5 MHz band to avoid the DXWW Contest and to try to find two of my amateur friends. Richard M5RIC was on the Isle Of Man for the contest (MD5K) and Bob M3DPQ who would be assisting with GB200CLB.

No DX was chased, as this would cloud the judgment. The next few trips if the weather allows will be for other bands and these will be assessed in a similar manor.
