If you want to build the same type of antenna as B&W has on the market, you 
will need an 800 ohm non ind resistor and a 16/1 balun...( there in lies your 
problem, building the balun )... The antenna can be anywhere from 60 feet to 
190 feet depending on the lowest freq you will be interested in. The balun goes 
at the feedpoint and the resistor goes on the opposite end,( you can use 50 
ohm coax to the shack ) just use 1/2 in PVC as spreaders and they should be 
about 18" in length.( not critical )  I've built 2 of them...One 90 ft the other 
190 ft...They work good for what there intended for, BROADBAND/NO TUNING... But 
you might be better off with a a ZEPP with open wire feeders into a tuner.!! 
If you go to the US PATENT OFFICE you can get all the specs on the B&W 
antenna. They make a good receiving antenna because there a closed loop ( quiet).
