A popular misconception about vertical antennas for the low bands is that they must have elaborate ground systems. Rx antennas at IV3PRK: building and testing the Waller Flag From modeling to the real life, where there is no free lunch. 5 turns on 80M) and the final MFJ-259 confirmed values are probably due to errors modeling an antenna this close to the ground, plus the fact that the coil wire leads add length to the overall antenna wire. That's because it's a full EZNEC v. The antenna is said to be compatible with radios that typically use a 15 foot whip antenna. I do not want my coax to radiate. EZNEC (and I guess any NEC) provides the ability to simulate transmission lines along with the antenna elements. The wire was connected to the bottom end of the shortest vertical wire and the length varied by a few tens of mm. In message , RST Engineering writes I tried simulating a Slim Jim in EZNEC and did NOT get the expected "aim at the horizon" low-angle radiation simulated pattern. 7 MHz RG-58 TRAP.

This hap-pens to almost any shortened or reduced-size antenna. EZNEC MODELS Height. On EZNEC, it appears to increase the resistance when the vertical is lower to the ground AND the resistance is higher when the ground conductivity is higher. More EZNEC results are shown below. 15 dBi), the LFA Yagi gain is 8. Back in 2011, the original author of HRD sold the rights to Ham Radio Deluxe to HRD Software, he cites pursing other interests as his primary reason for the sale, and states that he believes that the best way for Ham Radio Deluxe to continue on is for it to become a legitimate product, rather than a side project.

I'd like to discuss another option that hasn't gotten as much attention - short Beverage antennas. In a way, these losses are radiation resistances as they are resistances at the lumped impedance antenna input. As can be seen the drawing is based on an X, Y, and Z coordinates. Resources listed under Hex-Beam Antenna category belongs to HF main collection, and get reviewed and rated by amateur radio operators. 80 m 75 ohm VSWR. But his actual physical books were about Quads. I had been debating long and hard on a higher power rig for HF portable use. Several members of the Nashua Area Radio Club recently got together to help one of our members, Ralph N1UH, put up a 40m Delta Loop antenna. 0 Demo, except Using EZNEC to Model Antennas. he has done extenstive research om the subject and has published his results in QST and QEX with many of these articles available on the website. On CALIFORNiA musl irldude local slala sale. This calculator can be used to design a Slim Jim or a J Pole antenna. The feedline loss at the higher frequencies is considerable. A new ham on the HamRadioHelpGroup mailing list recently asked about what type of wire to use for building dipoles. SWR Bandwidth. 5 turns for the 80M coils. It’s no grand and a half a week that’s for sure. Thanks to W7EL and his EZNEC program it is relatively easy to compare different configurations of antennas for their RDF. It’s interesting how sometimes small side effects can add up over time to be a real problem.
