WebYes, height above ground can affect SWR as can the ground conductivity, so try to tune the antenna in a clear open area at an average height above ground that you think you would … WebDec 16, 2012 · When you go to tune your dipole keep in mind that you can fold the ends in about an inch at a time rather than cutting it. This way you can experiment more and not worry about going too short. Chances are though, being that low to the ground you are …

Lab Notes: Multiband Dipoles Compared - American Radio …
WebAn antenna that is 5% of a full half-length dipole isn't going to pick up as much RF as the full-length dipole, let alone a full-sized directional antenna pointed in the proper direction, simply due to the much smaller physical (antenna aperture) size. ... At HF, low-noise amplifiers are easy to design, and the ambient RF noise floor is ... WebA Multi-band Dipole or Doublet antenna system is a single length wire antenna useable on virtually any band where a tuner can provide a match. Efficiency is very good when the antenna is 0.4 wavelengths long or longer. ... Why you don't want to use coaxial cable when the SWR is high. For each 100 feet of coaxial cable, you lose half your power ... WebWhen you’ve finished trimming your dipole, you’ll probably end up with an SWR of 1.5:1 or less at the center frequency, rising to 2:1 or somewhat higher at either end of the band. … inclusive employers standard bronze
