    Hi,

    I was wondering what parameters in an antenna specification are important when comparing antennas. Specifically I'm looking at several options to improve RTK lock stability and accuracy in a noisey\multipath environment. The spec sheets I have either have superlative verbiage like "Superior multipath signal rejection" with no real data, or its a data sheet that im not sure what parameters to look at when trying to see if it indeed provides better multipath signal rejection.

    If anyone could help point me at what specifics I should be looking for and what parameters are key to differentiating between antennas, that'd be great. I attached the links to the antennas for reference.

    Also, sorry in advance if this is in the wrong area\forum.

    Thanks!
