Failure

Failure again.  This time it’s the fiberglass pole that has broken in half. Keeping a remote base running is a challenge.  A guy rope had slipped from it’s anchor allowing the top to blow over.  I am beginning to think using camo poles this high up is a hair brain scheme, especially after trying unsuccessfully to re-erect the pole today. This is what it looked like upon first approaching the site this morning.

Funny but performance had not diminished noticeably and this scene was a total surprise.  In fact just this morning I worked a station in Cuba on the 20 meter inverted vee and thought all was well.  Half of the vee is lying on the ground and the other half is running from the ground to the tip of the pole which is drooping down.  Low band performance seemed to be normal, too.  Go figure.  Also keep in mind this has worked successfully for over two months without the need of a site visit, through snowstorms, numerous thunderstorms, and a week of 90 degree heat.  No complaints.

Considering this antenna performed well when it was up I don’t want to change antenna design, only change the mechanical design. It needs to be stronger and easier to erect. Incidentally the purpose of the site visit had been to install a cable to make CAT work.  That was successful and the remote now has CAT control.

Update 6/23/2016:  A telescoping aluminum pole has been ordered as a replacement.  It is a DX Engineering ATK65A kit. It is a 65′ kit of aluminum tubing. The plan was to erect it only 39 feet and connect the inverted vee as a top hat just as before.  Then I remembered the modelling I did for a dipole which peaked at a height of 64 feet.  A real possibility for success could be to install a dipole at the tip using two Jackite 16′ fiberglass poles and run coax down the inside of the new aluminum tubing. That design would match the model with the most gain at 15 degrees take off angle.
