This antenna has several advantages that may help with radio range:
  • high gain (5 dB when compared to a 1/4 λ)
  • custom center frequency centered in the range of most RTK licenses
  • high quality TNC connector
  • 1/2 λ (wavelength) antenna that does not require a ground plane
  • appropriate for transmitters up to 25 watts

There is an advantage to using the higher gain antenna on both the base and rover.

The advantage of a 1/2 λ antenna over a 1/4 λ in open air is substantial.
Consider these common antennas:

compared with the iGA whip in open air with no ground plane:

Lower SWR is better, allowing more power to transfer between the antenna and radio.
