"For best results, the antennas are usually placed one wavelength apart. Because of the sheer size of antenna farms required, this is not often used at frequencies lower than the microwave band." - It's not clear whether the "this" in "this is not used" is referring to Antenna Diversity, or to spacing the antennas one wavelength apart.

Fixed. Thank you! --Mdwyer 03:30, 5 April 2006 (UTC)[reply]

Misuse of Antenna Diversity[edit]

I don't think this belongs on the main article, but I want to put it down somewhere.

It is important to note that the receiver only listens to one antenna at a time. It is a common mistake to attach an external antenna to a WiFi router and see no benefits, because the router chooses to use the internal antenna and ignore the external antenna. --Mdwyer 03:30, 5 April 2006 (UTC)[reply]

Usage in cars[edit]

A good example of diversity usage is in cars (AM, FM, TV). Most upper class cars (BMW, Mercedes Benz,...) employ diversity techniques in combination with rear shield antennas or antennas integrated in the trunk lid (BMW 6 series) to avoid stub antennas.

Types of diversity[edit]

It should be pointed out that there is spacial diversity (i.e. separation of the antennas) as well as pattern diversity (i.e. different radiation pattern characteristics). The mutual coupling of the antennas will impact the amount of diversity gain which can be achieved. The separation necessary to achieve significant diversity gain depends on both the wavelength as well as the radiation pattern characteristics. —The preceding unsigned comment was added by Sweden one (talk • contribs) 19:04, 21 January 2007 (UTC).[reply]

Under the heading, "Antenna Techniques", subheading "Polarization Diversity", I propose replacing the following sentence: "Additionally, such diversity has proven valuable at radio and mobile communication base stations since it is less susceptible to the near random orientations of transmitting antennas." with this one: "Additionally, such diversity has proven valuable at radio and mobile communication base stations since it is less susceptible to the near random orientations of mobile antennas." Is this correct?--107.207.57.122 (talk) 20:07, 5 November 2016 (UTC)[reply]
