Topband: Phased VLB to NA DL8LAS

[VE6WZ_Steve]

Andy,

What is the broadside spacing between wires?

I currently have 17 BOG wires, with 8 broadside phased pairs spaced at 400'-500’ (120m-150m).
Without doubt, these phased pairs eclipse any RX antenna I have used at ve6wz.

I will be interested to see how they perform for you.

The broadside spacing between wires is important to enhance RDF. On 160m, if spaced less than 100m then the RDF improvement will be limited.

Here is an older video I made explaining how RDF changes with broadside phasing distance:

In this video, I show drone data showing how a broadside pair compares to a single wire:

Thanks for sharing your data Andy, I will be looking for you on 160m!
