Install your completed DX Engineering HEXXAGONAL BEAM Mark 2 with a rotator at a height of at least 25 feet for very good results. The best overall results are realized with the antenna at 35 to 65 feet. SWR Testing HEXXAGONAL BEAM Mark 2 should not require tuning. -
Page 28: Single Band Wire Element And Wire Guide Package Instructions
The coaxial cable center conductor connection has red shrink tubing on the ring terminal. Exclusive DX Engineering stainless steel band clamp with welded stud provides a secure attachment for the driven element feedpoints without drilling. The high strength insulator features serpentine wire grip and stainless steel hardware providing superior connections for trouble free operation. - Page 29 Choose the band you are constructing and install the Wire Guide as shown below on a typical spreader positioned vertically. These assemblies will be moved for final positioning on your antenna. Snug them in place and do not tighten. 5-Band positions - Position depends on your band choice - Choose one Mount the Single Band Insulator Center Feed Clamp Assembly on the vertical post in the position for the chosen band.
- Page 30 Thread the other end of the two driven element wires (front of beam) with the black tubes and ring terminals through the previously installed wire guide clamps, positioning one of the black tubes through the clamp as shown. If the tube does not fit through the loosened wire guide clamp, you may need to nudge the installed clamp opening slightly (see below).
- Page 31 NOTE: Creating a 2-band antenna by adding a 1-Band Kit to a 1-band HEXXAGONAL BEAM may require special length jumpers and special element dimensions which may vary from the dimensions in this manual. The process of creating a two-band antenna has not been evaluated by DX Engineering.
