Now, using a very hot iron, sweat the connector flange to the tubing all around the seam. Use only enough solder to do the job. Allow to cool. Check for shorts with an ohmmeter. Next, clean all flux residues and you are done.
Alcohol is good for removing rosin flux.
Use only outdoors and away from fire as alcohol can be toxic and is highly flammable. If you have suitable equipment, check the antenna for VSWR at the freq- uencies of interest. Use Type N connectors and use adapters sparingly. You will probably notice improved UHF reception with this antenna compared with a whip or a large discone. We are using this antenna in conjunction with a spectrum analyzer and it works very well indeed.
