log periodic array

Baluns on Log Periodic Antennas - Some antenna manufacturers place baluns at the incorrect location in LPDA arrays, or tell you to route the cable incorrectly. This can cause substantial RFI and all sorts of weird problems like RF into house wiring.

A 5 band log periodic dipole array - Modified version of the Telerana antenna which was orginially featured in the July 1979 issue of QST.
