Hi John, N4NAB
To make with easy reliable measurements of the Incident Power ,Reflected Power and SWR from 1 watt to 250 watt at 1260 MHz and from 1 watt to 25 watt at 2300 MHz I suggest you to buy a BIRD Thruline Model 43 RF Directional Wattmeter with the approprate standard measuring elements depending on your needs. This unit is a professional instrument well know to all radio engineers and you can move it with easy from the shack to the antennas only screwing two N connectors. Using the appropriate measuring elements you can extend the frequency range from 0.45 to 2300 MHz I have two BIRD 43 since 1976 and I am very happy with them.
