I only want to cover 144 and 420, nothing in between! Just for LEO
satellites, where the uplink is on 144 and the downlink is 420, or vis
versa.

Then you would be wasting 98% of the frequency coverage
of the log periodic. The unused antenna elements would
constitute almost the total cost of the antenna.
