Simple Delta Loop 
for the 80m Band
 
 
Loop Dimensions;

Polarisation: Vertical
Wire Diameter: 2.50mm
Height at Peak: 14m
Length of Wire No.1: 40m
Length of wires 2&3: 23.8537m
 
Forward Gain: 2.25dBi@25°, 1.42dBi@15° & 0.02dBi@10°
 
 
(Notes: Wire 1 is exactly 1m above the ground  This antenna is great for the long haul QSO on 80m, I’ve got a lot of rare DX with this antenna!)
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Note: All calculations made using “Average” ground conductivity figures with “Copper” wire “Loss” taken into account.

I found this old picture of the 80m Delta-Loop up at the farm in France, thought it would be good to put it on the site !
