Right-slightly OT, for a mobile antenna, you will find that you can squeak out a bit more gain by using a .64-wavelength whip instead of a pure 5/8-wave (.625) In the late 60's/early 70's, the NewTronics BBL series VHF gain antennas were rated at an honest 4dB gain-and did it. The A/S VHF gain antennas measured about 2 dB. They were actually end-fed 1/2-waves... If you can find an original BBL-144 still in good shape after 30+ years, keep it! -- Jim Barbour WD8CHL
