Antenna Delta Loop Links →
Antenna delta loop 6 metri 50 MHz
Delta Loop, has a value of about 125 ohms, while its gain is about 1.4 dBd
6m Deltaloop
This delta loop for the 50 MHz amateur band is easy to carry out
Delta Loop UN7CI for 7, 10, 14 and 21- MHz
The antenna has SWR less the 2.0:1.0 at height of the lower side 1.2 meters above the ground
Delta loop rotable for 40 m
the delta loop has an impedance of about 100-120 ohms. a quarter wave of 75 ohm coax is used to transform the impedance down closer to 50 ohms
