Transmitter Attachments

We've included important application details for each type of attachment.


  • If not used as a Glue-on, may be surgically implanted under the skin of reptile. A small incision is made and a long hollow needle is inserted under the skin where the antenna will be placed.
  • The antenna is inserted into the needle which is used to pull the transmitter into place.
  • The incision is closed with 3 or 4 stitches.
  • Training is required to surgically implant the transmitter; involves recuperation period for the reptile.
  • Reduced field range compared to external transmitters.
  • Programmed options available on R1500 series'.

  • For turtles, attached to the carapace using various epoxy adhesives.
  • Glue-on’s are easily attached and removed in the field; little or no affect on turtle's behavior.
  • Field range greater for terrestrial than aquatic species (water interferes with the VHF signal).
  • Enhanced range option available on models with "B" suffix.
  • Programmed option available except on R1600 and R1605 series.

Body Implant - Coil Antenna

  • Used where external antenna may become tangled.
  • Surgically implanted into body cavity and sutured.
  • Minimizes fish behavioral change.
  • Field range 1/3 of trailing whip antenna models.
  • Extended range option available (B model).
  • Programmed options available.

  • Archive tags combine datalogging capability of specified sensors (temperature and activty, typically) along with a VHF beeper tag.
  • The archive tag must be retreived in order to download data from non-volitale memory.
  • Communication is via IRDA (infrared) wireless communication.
  • Typically used internally in fish, externally on reptiles.

Body Implants - External Whip Antenna

  • Involves surgically inserting a transmitter into the peritoneum cavity with whip antenna exiting through the skin.
  • Negates need for an external attachment to maintain acceptable field range.
  • Training is required to surgically implant transmitter; involves recuperation period for the reptile. This attachment does not change the reptile's behavior.
  • Good field range from the trailing whip antenna. Extended range available (models with "B" suffix).
  • Programmed options available.

Tracking System Options

GPS Systems

Today's GPS systems have come down in price and weight. ATS has models as light as 50 grams, which can be used to log GPS positions on a number of reptile species.

Remote Unattended systems

Many presence-absence studies involving reptiles use one or more data-logging receivers located in strategic positions.  These stations can be provisioned to operate unattended for months using battery packs and solar panels.

Mobile Tracking systems

If you can drive or boat in, you can mobile track. You can use a simple hand held antenna, but to increase range, use a larger antenna mounted on a mast.

Manual Radio Telemetry

Homing, pure and simple, with maybe some triangulation thrown in, to locate your animal. Your range will vary and is dependent on line-of-sight between your transmitters and your receiving antenna.
