Specifications of the stock monopole antenna of the LimeSDR kit

Hey guys, I’m using the Lime in my final year project and I need to put in a few details about the antenna I’m using. If I can get a hold of a better antenna before the deadline, I’ll switch. But having a few tests with this one won’t hurt.

So I need a few credible sources that I can cite that tell me things like the frequency response, gain and maybe noise figure. Any idea where I would find one of these for these antennas?

Alternatively, is there an antenna similar to this that I can compare it to?

Hello @Fshkie,

Here are a few links that might help you to measure any antenna parameters:

As a side note, I’m not an expert, but I’m not sure whether noise figure is an antenna’s parameter. You might want to re-check this.

Well, according to the description on crowdsupply:

  • Antennas are omni-directional
  • Antennas tuned to the major bands: 800-960MHz / 1710-2170MHz / 2400-2700MHz

Unfortunately there are no details regarding gain, structure (whip / spiral / …) etc. I believe you can compare these antennas to any antenna designed for same frequencies. Lots of antennas are available on EBay and AliExpress.

Awesome, thanks afriskon. You’re killing it today :ok_hand:
