I know it's a different answer... but Be careful about RF coming back in on the RX antenna to the radio, Some radios have issues with even quite low levels (~100mW) comiing in the RX antenna port. the internal isolation may on the face of it appear good enough but any residual leakage is occurring into low level stages that may be in the TX chain with 20 to 40dB gain, add in an external linear and even a small amount of RF being picked up by the TX antenna may be enough to seriously degrade the quality of you transmitted signal. In particular look out for any change in ALC action with the RX antenna connected as this is a sure sign that all is not well
