Roger, I have used Hygain dipoles and multi and single band beam antennas
since 1958 and have always admired the mechanical design and directivity.
Now I have to admit I am getting worried about trap loss.
I would be interested in knowing the coil Q, but more specifically, how a
trap beam (Iike the TH3 I am currently using) compares to a dipole at the
I was told by Ken (I forget his last name) at Dayton many years ago that you
used to measure ham antennas on a range, but last year at Dayton the fellow
who designed the 12-17m sleeve antenna told me the range is only used for
commercial antennas now.
Do you think you could steal a little time on the range and do an actual
trap beam to dipole comparison?
