Frequently Asked Questions

1. Can I modify the 40m (130') length of RG213 coax cable that comes with my AD510-10 Active Antenna?
   No, you cannot modify the RG213 Cable supplied with the AD510-10 Active Antenna. Doing so will effect the power and specs to the antenna and cause failures.
2. Can I use higher grade coax cable to extend the run of the Iridium AD510-10 Active Antenna?
   Yes, there are several options to extend the cable run outside of the standard 40m (130') RG213 coax cable.
   
   1. LMR-400 with N connectors will allow a run of 65 meters exactly
   2. ECOFLEX 15 with outside diameter of 14.6 mm and N connectors will allow for 80 meters exactly.

   3. LMR-600 with N connectors will allow a run of 100 meters exactly
3. How close together can I put my Iridium AD510-10 Active Antennas?
   The minimum distance between any Iridium antenna, active or passive, is 1 metre. This is the absolute minimum and a larger distance is preferable. As in all RF applications the greater the better. We normally advise a min of 1.5 metres for Iridium but we do have customers running five (5) AD501-10 Active units on a single mast at a spacing of 1 metre between each.
4. What is the added gain of the AD510-10 Active Iridium Antenna?
   The active antenna has no system gain and is built so the radiated power is that of the standard Iridium handset. I.E. +38dB. The AD510-10 Active Antenna is not built to add gain to the system, as many people believe, but is made to place the antenna in a more suitable position. The active antenna can ONLY be used with the set length of coax feed and CANNOT be changed as this forms part of the operating specs. If the feed coax is changed it can damage the Active elements in the unit.
