Hustler 4-BTV – Initial measurements

Here are some initial measurements for the temporary installation of the 4-BTV. These measurements were made at my station (100 feet of RG-8X connected to the antenna which was connected to approximately 50 feet of RG-8U that leads in from a workshop to the station location.) The antenna was set at the starting dimensions stated in the assembly manual and is on a temporary vertical mount with sixteen 30 foot radials in a wide open space at least 50-70 feet away from any structures.

Obviously some tuning is in order, at least on the 40m band but for a temporary mount and sixteen radials it seems to be performing well.
