Hi Ron,
A short Beverage -- regardless of its velocity factor -- has the radiation pattern of a short Beverage. You can't improve the performance of a Beverage antenna by lowering its velocity factor. That's why BOGs have a radiation pattern similar to an elevated Beverage of the same length, except that a BOG has more loss than an elevated Beverage especially for signals arriving at low angles. A BOG is an excellent choice when stealth is the driving requirement, otherwise arrays of short verticals provide significantly superior performance compared to BOG or short Beverage occupying the same physical space. 73 Frank W3LPL ----- Original Message ----- From: "Ron Spencer" <ron.e.spen...@gmail.com> To: "Topband@Contesting.

While adding cores along the length of a beverage may make it appear electrically longer, how can that help its performance? I'd think that the true mechanical length is what matters. Each inch/ foot/ meter of the wire is what "gathers" the signal. A 300' (actual length) will gather more signal than a 200' beverage. Making it look electrically longer won't change this will it? Same as a 100' tall tower will be a better transmitting antenna than a 43' one.
