|iGA UHF Antenna
This UHF whip antenna is a
custom full size ½ λ end-fed whip antenna
with 5dB gain and a Center Frequency of 462.888 MHz. It includes a
adapter and is suitable for all RTK GPS receivers with a standard
TNC antenna connection:
ProCom PN 140000182 + PN 140000031
Length 1.23 feet.
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
(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
in open air is substantial.
Consider these common antennas:
compared with the iGA whip in
open air with no groundplane:
SWR is better, allowing more power
to transfer between the antenna and radio.
