Hi Justin (G0KSC),
I am writing to thank the design of the OWA 10m / 5 elements antenna that is available on your webpage.
We built the antenna and it showed excellent results:
Without the choke:
SWR = 1.1 from 28.000 MHz to 28.300 MHz
SWR = 1.0 from 28.350 MHz to 29 MHz.
R = 55 Ohms and X = 0 Ohms. (on MFJ-259C)
SWR = 1.0 from 28 MHz to 29 MHz.
R ranging from 47 Ohms to 57 Ohms with X = 0 Ohms to X = 5 Ohms, depending on the frequency.
Let's now build an OWA for 15m / 5 elements.
We thank you and invite you to visit our website (PR1M) on QRZ.com.
Many thanks Justin.
