GPS Antenna

Product Details

All 4 antennas are magnetic mounting, patch type antennas, since these are the

best type to use for the automotive application where they can simply be placed

on the top of the roof.

Our standard antenna should give excellent performance for over 95% of customers

needs, and is shipped as standard on all of our products. It is an excellent antenna,

at a very competitive price point.

We also stock an RF-interference rejecting antenna. At some locations, RF interference

has been found to be a problem, causing loss-of-lock of the GPS signal from the

standard antennas. This typically occurs at professional motorsport events, where

outside broadcast vans, and telemetry from other devices, creates an extremely noisy

RF environment. In these situations, we have found that our RF-interference rejecting

antenna will retain lock where the standard antenna cannot. However, this comes at

the price of slightly increased noise on the data, so this antenna should only be selected

where an RF interference problem is either suspected or been identified.

We also stock a low-noise antenna. This antenna has been found in testing to give slightly

lower noise on the signal and data received under some circumstances. For most customers,

this is unlikely to give any perceivable benefit, and we would recommend selecting the

standard antenna. However, some customers, particularly in the industrial testing sector,

may find this antenna gives some improvement in the quality of the recorded data.

This antenna may be of particular interest to those using the SPEEDBOX-RTK unit, since

this antenna may sometimes acquire or retain an RTK lock where the standard antenna

cannot, when the GPS signal quality is marginal for the RTK system to lock-on.
