One must question the charts.  I don't see two antennas having
identical gain (to 0.01 dB), F/B or F/S, or SWR Bandwidth on
every band.  In fact, the SWR curves published for the two
antennas show the 1.5:1 and 2:1 bandwidth is *different* for
the two antennas even if they adequately cover each band.

Ron,

The gain and f/b charts for these two beams are identical:

https://jkantennas.com/jk-navassa-5.html

https://jkantennas.com/xr5.html

Both have two elements on each band.

The XR5 has a longer boom and a wide gap in the middle so it can be
side-mounted on a tower.

Has anyone done a comparison between the Navassa5 and XR5-JK 5 band yagi's?

Due to tower/yard restrictions I would prefer the Navassa as long as
performance is similar to the XR5
