WebAug 5, 2024 · At frequencies where the counterpoise is a 1/4 wavelength or multiples of 1/4 wave it would become the dominant counterpoise. At other frequencies RF currents would divide between the counterpoise and coax shield depending on their resonant lengths. A counterpoise wire will not keep RFI in the shack from riding up the coax and being …

WebJul 20, 2024 · With a very short counterpoise it is difficult to resonate the fundamental with any drive impedance. Increasing the drive impedance tends to move the resonances to slightly higher frequencies. Adding an additional 2 meters to the counterpoise did very little to affect the resonant frequencies, much less than adding that length to the main wire ... WebPalomar Engineers employs a dual core matching system that offers wide bandwidth (1.8-61 MHz), 500 watt PEP rating, and a connection for a counterpoise or ground if desired. The antenna can be used as a sloper, “L” with a vertical section and a longer horizontal section, or as a random horizontal antenna between two trees or supports.
WebAug 15, 2024 · wires or other conductors in a circular arrangement at the base of an antenna system at a specified distance above ground are called counterpoise in … Web•Lacking any deliberate counterpoise the return path IS the coax shield, which is an ambiguous/random element •Recommendations are for a 0.05-wavelength radial tail (at frequency of use) •Adding a choke to the feedline at the match may not help or prevents shield from being counterpoise. Choking at radio may protect it.

WebFor example, if you are getting RF problems on 20m (14MHz), a PVC-coated wire or counterpoise cut to a length of 5m may resolve many of the EMC issues. The W3EDP end-fed antenna is a cheap way of getting multi-band operation, especially if you are a newcomer and restricted to 10W. Other pages in this section – Antennas: Antenna Safety
WebDec 11, 2024 · The counterpoise that makes the vertical monopole behave like a λ/2 dipole on a HT is the operator’s body.
