New! Active Broadband Isotropic Antenna: Omnifield Antenna® OFA-G

OFA-G USB SA PC 1OFA-G_with SA in hand_2

Our unique active broadband isotropic antenna OFA-G: 30 MHz-6 GHz, 0.5 mV/m-50 V/m.

for selective RF spectrum monitoring and field strength measurements. Antenna head has 3 internal orthogonal antennas.

Signals from each antenna is proportional to the absolute value of the field strength regardless of the field direction.

Use it with your existing spectrum analyzer or we will provide two models of our spectrum analyzers: SA-S (up to 4.4 GHz) or SA-J (up to 12.4 GHz).
