The most difficult part of the entire assembly was finding fasteners for the boom tubes. I used four “JBL 63 cross parallel clamps” from UKW-Berichte, a renowned German company that also sells all kinds of antenna accessories. These clamps are inexpensive and perfectly suited for the 4-meter Spiderbeam boom tubes, of which I only used 3 meters. It is important to place foam rubber under the clamps everywhere to protect the mast and NEVER tighten the clamps too much. It is better to tighten them one turn too little than one turn too much. I inserted the AziLoop radials directly into the tubes and secured them at the front end with small duplex clamps to hold the wire in place. I used insulated 1.5 mm² electrical wire for the entire antenna, as there is no significant mechanical stress here. If the wire proves to be mechanically vulnerable, I will replace it in the fall with the high-strength wire also used for the Beverage antenna.
