Latest in the tape measure yagi antennas

This author has taken the tape measure yagi antenna project one step further.  Completing another 4 element tape measure antenna, I  decided to try and stack the two yagi antennas 1/2 wavelength apart and co-phase the two together.
Remember when co phasing antennas, the feed lines are exactly the same length.  To achieve this, I changed coax feed line to LMR-400.
Preliminary testing is generating some good results.  Have been able to access distance repeaters that I was unable to with the rubber duck antenna on the HT.

This is the test station in operation.  HT is a Icom T2H with extension mic, on 1 watt output power.
