[TowerTalk] Building Two 80m Delta Loops at Right Angles to Each Other

[Richard Thorne]

I want to build two Delta Loops for 80m perpendicular to each other with 
both apex's hanging off the top of my 78' tower.  I understand that I 
need to open the top of the delta loop that is not in use to reduce 
interaction.

Will a normal relay work here or do I need to consider using a vacuum relay?
