================
Nice URL with excellent info


The problem with ugly baluns is their limited frequency
ranges. In the following measurements, the choking
impedance was over 1k ohms for only small ranges of
frequencies, 19-29 MHz, 10-22 MHz, 16-25 MHz, 8-16 MHz,
5-8 MHz - frequency ranges of 2/1 or less. HF covers
a 10/1 frequency range.

I noticed the use of a lot of tie wraps. Its never a good idea to use
these exposed to sun light.
