Hi Cal, you have almost perfect ground situation with your radial field, take advantage of it by using RX vertical arrays, either some flags, arrays of them for particular direction, or switchable ci
While getting ready for the CQ WW 160 m Contests, please check the updated records for any "holes" in the records that could be "fixed". http://www.k3bu.us/cq_160_m.htm If you see any errors or omiss
Anyone has idle station or needs operating help in CQ 160? K3BU will travel and operate for food, jus' tired from resort business and need a radio break. Yuri, K3BU.us _______________________________
Mis tres centavos: I think you are right on! There is confusion what is radial - as part of resonant antenna radiator vs. ground (plane) One has to look at the current distribution curves in EZNEC an
Here we go again, speaking of misinformation, peer review, spreading false "guru" stuff. You can not apply Kirchoff law from DC circuits to the current behavior along the STANDING WAVE RF radiator. C
Sooo, there is no current and voltage variation along the standing wave resonant dipole? Soooo, Jasik et al, all those antenna books, modeling programs showing RF CURRENT and/or RF VOLTAGE distributi
Why solder? Jus' clean and twist wire ends together and screw on wire nuts (orange ones so deer can see 'em) Have them pointing up or wrap with electrical tape. You end up with joint that can be open
My 2 kopeikies: Ground characteristics vary from antenna base out, and down. We hardly know what is in the ground, could be clay, sand, rock, water, ???? It really boils down to two extremes: 1. Sal
Hi Ed, First question is about the QTH, ground conditions. Close to salt water or sea of sand? That would help deciding on polarization. Inv Vee is not a bad performer and horizontal loop would have
Scientwists are trying to "prove" that it is all human fault, causing global (warming) climate change. The reality is that we are getting just about all energy from the sun. We know about the sunsp
Hi Mike, As far as the ducting goes, here is some insight into the phenomena in my old CQ article: http://k3bu.us/propagation.htm 160 exhibits peculiarities, depending on sunspot cycle, time of the y

Oh, here comes the "guru" again. :-) Unnecessary debate? We are talking about experiences and RESULTS of comparing normal in land "ground" effect vs. salt water beach or marshes. We are commenting on
