If you have a choice as to direction, you want the wire to point towards the stations you want to hear. (for MW/BCB, I'd look at a heading of 45 degrees, which will favor both the Northeast and Europe) I thought that perhaps long wire antennas were most sensitive to stations at right angles to the wire..either side. If that is correct, Europe would come in best if the antenna was going north and south. Please correct me if I'm wrong. OK, you're wronggrin... As Dale says, the directional characteristics of a longwire antenna vary considerably with wavelength. However, a longwire antenna also must be elevated above earth. A Beverage antenna is close to the ground. Traditionally roughly 2m (6'), though recently BCB DXers have been having considerable success with very low Beverages. (mine is 140m long and about a foot off the ground; some DXers have been laying insulated wire *on the ground*) Mine is fed with a 9:1 balun (high-impedance side connected to the antenna), with a ground rod driven at the feedpoint. The far end is connected to another ground rod, through a 470-ohm resistor. This antenna - close to the ground and terminated at the far end - has predictable directivity, favoring the end with the terminating resistor. -- Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com |

Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com At your web page, I found your AM DX log which you referred to as "pitifully small". http://home.earthlink.net/~w9wi/articles/amdx.htm 294 entries is pitifully small? I'm wondering how large the AM DX logs of some of the other readers are. I'm certainly the newest of newbies, but 294 entries sounds pretty good to me! If that's pitiful, what would be considered impressive? |
