One thing that worries me about this TX is that there is no harmonic filtering. Need to check the output with a spectrum analyser or receiver tuned to likely harmonics.
With my background in video design, if the 1496 output alone isn't enough, I'd stick a wideband opamp on the output. The EL2020 was the archetype. That would easily deliver a few volts p-p into 75R. It's not the way an RF designer would do it, but I don't think of myself as an RF designer.
