Well, I did it.
I went ahead and purchased (on sale!) the snap on spreaders made by 73CNC. I purchased enough to make 100' ft. of line using wire I have on hand, #12awg solid THHN. The shipping was super fast, and the product looks to be of good quality. After reading some posts on other forums, I found that it's a good practice to put the spreaders in warm soapy water before snapping them onto the wire. Makes perfect sense to me.
I'll report on how the project goes. I am excited to finally get going on this. Having this up in the air by the
time I deploy the BC-610E will be a very cool event, just in time for the approaching fall and winter months.
