How will I know which frequencies I need for my tag(s)?

There are several factors to consider when selecting the proper radio frequencies for your tags.

Do you already have equipment for a specific frequency?
Does your organization or country have any frequency preferences or requirements?
Are there any interfering sources in your study area that you should avoid?
Are there any other studies taking place in or near your study area?

We stock crystals for frequencies in the 148 to 150, 164, 166, and 172 MHz bands.
Custom frequencies can be ordered but usually require 6 to 8 weeks for delivery.
