They may not be exactly the same due to component tolerances in the
wattmeters.
I am not sure what your goal is in asking that question. If it is a
quick check on your antenna syst
Actually, it doesn't. Slap a flat plate over the end of a zero length waveguide
and the SWR is infinite. Insert whatever you want in front of that and the SWR
may measure something different, but it's still infinite:-)

If your TX sensor is in line after the KAT500, you might be observing the
SWR of the antenna side of the ATU. The KPA500 and KAT500 LEDs show the SWR
at the transmitter

the ATU when it is in Bypass.

Using my K3/KPA500/KAT500/P3+SVGA with the TX sensor in line.
On the KPA500 the SWR reads 1.3 with one or two SWR led's lit also one or
two led's lit on the KAT500 but the SWR display on the P3 shows about 6.
Any idea

Hi Guys,
I put up Bobtail Curtain antenna for 20 meters for the CQ DX contest
this afternoon. It is fed at the center vertical element. Here is the
problem. It requires a matching network (tank circuit) at the feed

As long as you back down the power appropriately I think you will be fine.
However, your amplifier would work better if you put, for example,
a pi network at the input. This will give a low impedance path for the
second and higher harmonic energy in the input circuit and improve the
efficiency. Yo

HI REF, but seems to suffer no harm. Is that too high an SWR, and does this
condition lower the quality/purity of the transmitted signal??
