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)

With choke:

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.
