LDG RBA-4 - 4:1 Voltage Balun
Review by
ken M0BQH
I purchased this item due to a tubetube channel by K4OGO for the coastal 20 vertical antennas using different balance and UNUNs, I followed the instructions of using a total length of 29ft wire to make an OCF Vertical using this Balun, The upper wire was 25ft the lower wire is 4ft and this has incredibly gave me operation of the 80m to 10m bands, This is a good quality piece of kit

Simple low loss alternative to patch lead.

I needed to connect a 4:1 balun for a doublet to 1:1 RF choke to prevent RF in my shack. Rather than using patch lead to connect the two I decided to connect them direct without using a patch lead. Seems to work well.

Typical LDG quality

Not the cheapest balun but usual LDG quality. I'd considered making my own but after pricing all the components - toroid, case, etc. it wasn't much more to buy ready made. I've made a temporary doublet just to run some comparison tests with my fan dipole. The doublet using the LDG 4:1 balun actually outperforms the fan dipole on some bands so its going to be added to my collection when I have time.
