I am looking for the hole measurements for the Altus Metrum TeleGPS?
4-40 screws. I looked on the Altus Metrum site for a template but they didn't have one listed for the Tele-GPS. I used mine for the pattern for the sled. Kurt
Thanks Kurt,
Chris from Chris' rocket supplies also sent me an email with the following:
"hole pattern is a rectangle 1.25 x 0.75 inches, holes 4-40 / M3 screws"
Now I just need the length of the wire antenna?
Now I just need the length of the wire antenna?
about 6 1/2 inches. 1/4 of the wavelength, which, for 435MHz, is about 6 3/4 inches, then adjusted for the velocity factor of a copper wire (around 95%).
