Calculator - Dipole & Inverted 'V'
Use At Your Own Risk
Maple Leaf Communications assumes no responsibility for material calculation errors or other deficiencies in the calculator offered here.
Installed antennas can be affected by buildings, trees, mast properties, other antennas, ground conditions, and more.
Dimensions reported by this calculator should be considered only approximations of the length(s) of material required.
When ordering materials and building your antenna, allow a little extra length and trim as necessary instead of building and installing the antenna before discovering that it is too short.
The Half-Wave Dipole & Inverted 'V'
The very-popular centre-fed, half-wave dipole and inverted 'V' antennas can be calculated below.
The basic formula for the half-wave dipole is 468/freq (in MHz), but it can be modified below to your needs.
When the dipole will be installed in an inverted 'V' configuration (rather than straight-horizontal) the formula should be modified to reduce the length . A percentage adjustment can be entered below according to the following guidelines:
