When there are antenna problems, here's a couple of units
that I have used. BP CB195 SWR/Power Meter, 10W/100W, 30 MHz-300MHz; Calrad
Radio Field Indicator, Model R.F.-8. The first allows you to check your radio's
power out and your transmission line-antenna impedance match. With the
second, you take your plane out in a flat area and with someone transmitting on
various frequencies, walk in a circle around the plane while noting the received
signal level. This will show you how even the radiation pattern
is.
