Do you have some tips for antenna selection?

Some antennas require the use of a ground plane for optimal performance. Generally this is a 1/4 wave monopole antenna type design. Generally these types of antennas don't perform as well and are not as efficient but are economically priced.

Some antennas are ground plane independent and do not require a ground plane for optimal performance. This type is generally associated with 1/2 wave bipole antenna designs that perform better, are more efficient, and may demand a higher price.

Detailed antenna specifications will show quarter wave or half wave, monopole or bipole.
