Priming Aluminum Antennas

The hard to acquire Zinc Chromate PrimerIf you have been reading this web site you will recall I have paid much attention to the 43 foot antenna manufactured by DX Engineering and Zero Five Antennas.

After much simulation and trading the benefits against pitfalls, I purchased the DX Engineering 43 foot antenna kit with the balun.

However, a shiny aluminum antenna in the back yard would attract the kind attention I just don’t need. Research on the Internet reveals several solutions including:

Ham Question: Coax Loss and Remote Tuner for 43 Foot Antenna

A reader asks…

I am thinking about getting a 43′ vertical to use on 160 to 10 meters.

Has anyone calculated the coax loss for 100 feet of RG-213 coax, especially on 80 and 160 meters?

Would it be beneficial to build a remote tuner [like below] and place it at the base of the 43′ antenna to reduce coax loss?

DXE knows how to package their products

This is a bit silly of a post for an amateur radio web site.

Ham Question: Kenwood TM-G707 Display Erratic

Hello all,

I wonder if any of you had your display unit for your Kenwood TM-G707 2/440 transceiver go blank and reboot even while the radio operates just fine.

If I move the wire with respect to the control head in a certain position this happens.

Is this just a case of dirty contacts between the little cable adapter and the control head or have any of you seen the wire in the cable actually break?

Old DX Engineering Radial Plates won’t fit 2 inch OD pipe


About two years ago I received a DX Engineering Radial Plate for Christmas. Nice gift for a ham eh?

It has been serving as the focus of twenty-eight 33′ radials and a 16.6′ vertical antenna for over a year with great results. A QSO, a 20 meter phone QSO, with a station in Australia was the highlight. Okay he had a stack of four 20 meter beams phased and pointing straight at me, but it still makes me like my dirt based 20 meter vertical.
