Wire Antennae Various wire antennae are also used at different stages for experimentation purposes. I have had very good success at my previous QTH with Off Centre Fed Dipoles. Over the years many types of wire antennae have been tried and I guess that is a result of having spent most of my ham radio time in a big city on an average suburban block. Plans are to soon put a multi-band dipole with open-wire feed line for use mainly on 160-40 m. |
Antenna switch A remote 4-Port antenna switch is used to select between the different antennae from within the comfort of the "shack". The switch is controlled with a Pic-Axe 08M controller to both select the appropriate antenna and to display information on an LCD. As different Antennae are changed / replaced, the Pic-Axe is reprogrammed with appropriate information. A band switch data input available on most modern transceivers was considered but in practical application it is much easier to change between antennae based on propogation, not band. |
Equipment on HF Various transceivers are used at my shack, and most don't last long due to my penchant for trying most rigs on offer. Over the years I have tried just about all transceivers and will enjoy continuing to do so! In August 2019 I put the final covers on my completed Pic-A-STaR Transceiver and have now built 3 versions. |
