Web(1) Parabolic or dish antennas are NOT frequency dependant. That is any dish will work to some degree at any frequency. The basic determining factor is, how many wavelengths in diameter is your dish? The more wavelengths the more gain. For instance, an 8ft dia dish has about 28 dB of gain at 1296MHz, the same dish has 45 dB of gain at 10368 MHz. WebEnter the diameter of your parabolic dish in m (metres) and the operating frequency in GHz (Gigahertz) A typical VSAT is 1.2m diameter and transmits at 14 - 14.5 GHz. The calculation results are:.
