Abstract
A helix antenna and methods of making and using helix antenna to concurrently or independently radiate pulses in a very high frequency (VHF) band in a range of about 240 MHz to about 270 MHz and/or in an ultrahigh frequency (UHF) band in a range of about 360 MHz to about 380 MHz which can be useful in space to ground data transmissions, subsurface radar, and measurement of ice and snow pack.
