Mounting the 4-BTV on towers, tripods, or large mast pipes, approximately a quarter wave in length, can often provide an upset to the counterpoise created by the radial system, and act as a vertical dipole instead of the desired ground plane. Position the 4-BTV base on this pipe to a location not exceeding four inches of separation between earth and coax connection. There is a concrete patio to the left of this photo only 1 foot away. This arrangement will create six 6 2m long radials spaced 60 degrees apart. Fabrication, furnishing and installation of chain link fence, chain link gates, and extension brackets with barbed wire.
