For 20 m traps use 9 turns of wire on a 42 mm PVC pipe and 500 mm of RG58 coax to begin with. In addition, a trap-dipole will perform no better than a dipole, because that is what it is. Traps for different bands can be combined onto one dipole to create a single antenna tuned for maximum gain on all your favorite bands, from 160 to 10. iPhone 6 deals. China Bucket 50. the 10-meter trap, then slip the unswaged end of the 15-meter, driven element trap into the 1" x 5" section of tubing. A trap is a parallel resonant circuit network that can perform either of two functions in an antenna system, depending on whether or not the traps are resonant at the operating frequency. This pattern is at odds with previous estimates of deep transfer efficiency derived from bottom-moored sediment traps, but is consistent with upper-ocean flux profiles measured by neutrally buoyant sediment traps, which show strong attenuation of low latitude particle fluxes over the top 500m. Since survivors run at 4 meters per second, that means that a survivor has the ability to run 28-36 meters to the nearest safe zone.
