High Quality Balun  Time owned: more than 12 months
I have 2 of these. The first is circa 1988 and has stood the test of time perfectly. I was so impressed with its durability that I jumped at the opportunity to pickup another 2nd hand unit in 2009 for portable operation.

The BL-50A is a fully sealed unit and as such is inherently weatherproof. No rubber seals, silicones or other such weatherproofing needed.

These were sold locally in VK/ZL by Dick Smith Electronics years ago when they serviced our amateur community.

If you need an inexpensive 1:1 balun that has very high resistance to the weathering, I thoroughly recommend this unit.

The only design deficiency to my mind is the lack of a vertical support hole or hook. It was not necessary in my installation, so I am not marking it down for this. I can imagine for centre mount point installations, this might be overcome by using a small piece of weatherproof rope between the horizontal support holes as a vertical attachment point.

Primo !  Time owned: more than 12 months
I have one installed on a homebrew half wave single wire dipole with links for 80m/40m which is used for field comms.This has given trouble free operation over a ten plus years.Another is installed at home QTH as the centre feed point for a two wire dipole on 80m and 40m.This has been in use now for 9 months.The original baluns hardware did not show signs of terminal corosion but the newer one has so I replaced with stainless steel.As most balun manufactures specify keep the antenna tuned for resonance,keep the tuner in the cupboard and you should not have a problems.
