The Antenna is in size 2.6m x 2.6m and has a total size of 6.76m². Cobweb Antenna MFJ-1838 40m - 6m 8-Bands 1. MFJ HF Cobweb Antennas are relatively small in size, are light weight, and are low cost. An antenna analyzer was a big help while tuning and the additional wire needed was easily spliced together and soldered. Social Plugin.

works best on HF below 10 MHz since these high angle radio waves are reflected back to Earth. Most often a low dipole is the best antenna to use and will provide reliable communications. This makes a NVIS antenna an excellent choice for emergency communications and for staying in contact with other amateur radio operators in nearby locations.. this page aria-label="Show more" role="button">.

The antenna impedance matching components (BOX “Z” above) to match the antenna impedance to the coax line impedance (usually 50 ohms). For non-resonant end fed antennas, the typical feed point impedance is 300 to 600 ohms and a 9:1 impedance transformer (e.g. 450 ohm average antenna impedance to 50 ohm coax, also know as a 9:1 unun)..

Today I'm building an HF monopole for 20 meters. I go through a basic formula, for fun we model the antenna in MMANA-GAL, then I show you how I put it togeth. For vertical antennas with a feed point impedance less than 50 ohms, you will need a sub-ratio impedance transformer (e.g. 25 ohm load to 50 ohm coax, also know as a 1:2 unun). For vertical antennas with an impedance greater than 50 ohms you will need a step up impedance transformer (e.g. 100 ohm load to 50 ohm coax will require a 2:1 unun).

Distance Between Two HF Vertical Antennas . The simple answer to this intriguing question is that for a minimum frequency antenna you need to maintain a distance of at least 1/4 of the wavelength, which must be kept to a minimum. In the case of VHF antennas , this distance is 19 inches. In this case, the issue of destroying one radio and another.
