  FAQ's
1. Why do you (iGage) bundle the receiver with an antenna and cables?

After many years of supplying repeater and high-powered radios we have found that most antennas and cables already deployed in the field have:

Bad bottom mounts which make poor connection
Bad antenna cables, closed in carry case hinges, whipped in the wind with broken conductors
Bad TNC (or BNC connectors with lossy adapters)
Missing antenna ends
1/4-wavelenth, unity gain antennas which require a substantial ground plane to deploy

By supplying a great antenna in known good condition, we expect your experience with our radio solution will be be exceptional, out of the box.
 

2. Is the iGR supplied antenna (iGA5) compatible with other NMO mounts?

No. Because the connection clip on NMO mounts is unreliable for antennas that are setup and taken down daily we direct connect the coax cable to the antenna. The iGA5 antenna is NOT an NMO mount antenna. The antenna can not be disassembled at the base, it can be unscrewed in the middle which makes it easier to transport.
 

3. Is the iGA5 supplied antenna a good solution for other applications and radios?

Probably, the cable has a standard TNC connector, the bandwidth is wide and the SWR is low:

 

4. How long is the coax cable on the iGA5 antenna?

5-meters (16.4 feet).
 

5. Will the iGA whip antenna work directly connected to the iGR radio?

Yes, it works great directly connected. Because there is no coax loss when directly connected and the iGA antenna has lots of gain you should limit the output power of the radio to M-Medium 20 watts so you don't exceed your license's ERP.
 

6. What formats are supported by the iGR radio?

The following formats are narrowband compliant and suitable for use in the USA:

Satel 9600 FEC ON, Satel 9600 FEC OFF, Satel 19200 FEC ON, Satel 19200 FEC OFF
TT450S 4800, TrimTalk II 4800, TrimTalk3 9600
Transparent EOT 4800

Also, check out the [ User Manual ] for additional information.
 

7. Will the iGR connect directly to a GPS instead of repeater use?

Yes, it has standard Tx Only and Duplex modes. Your existing cable will probably work.
 

8. What is the difference between the iGR radio and other Harxon eRadio variants?

The iGR radio has special firmware that eliminates non-compliant modes and operation for use in the USA.
The iGR radio is supported, warranted and serviced by iGage Mapping Corporation.
 

9. Will my receiver be able to directly control the iGR radio, changing frequencies and modes?

No. You will need to use the front panel on the iGR to make changes.
 

10. Does the iGR support CSMA?

Yes. It can be turned on and off from the front panel. Most users should leave it ON. However, because we expect some applications to have dedicated frequency assignments it can be disabled.
 

11. Is the iGR as finicky about supply batteries as other radios?

No, and the iGR has a built in voltmeter so you can tell the charge state of your battery.
 

12. Is a programming dongle required to modify frequencies and bandwidth?

No, However, a special, unique, secret, code is required to modify the radio frequencies, channel bandwidth and channel assignments. The code is available in a sealed envelope from the factory and allows a technician to modify frequency assignments. Every radio has a different code.
 

13. Is a FCC license required to operate the iGR?

Yes. Absolutely, an FCC license is required! Checkout this American Surveyor [ article ] for additional information.

If you apply for a license, the [ User Manual ] section "Obtaining a New FCC License" has the information you that may be asked for by a license coordinator.

There are no itinerant frequencies that the iGR can operate on without a license.
 

14. Will iGage program the radio prior to shipment?

Yes. If you have a FCC license, we will program the radio with your licensed frequencies prior to shipment. We will print out a reference copy of your license and include it with the radio and we will make a label with your FCC Call sign and put it on the front of the radio.

If you do not have a FCC license, the radio will ship with NO programmed frequencies. Your supervisor or radio technician can setup the radio after you receive authorization from the FCC.

Check out Mark Silver's [ Blog post ] for additional information.
 

15. How far will the iGR transmit?

It depends:

No other users or interference on the frequency
iGR's Radio antenna put 10' above ground level
Good Rover antenna
Clear line of sight (radio location elevated so that earth curvature and trees don't block the signal)
Fully charged battery
FEC ON

We expect well over 25-miles.

If there is not clear line-of-sight or there is another user or interference on the frequency then you might only get a few miles.

We do test the output power and the iGR is comparable to other 35-watt radio solutions.
 

16. 900 MHz?

No.
 

17. Works with other GNSS receiver brands?

If the other receiver uses 400 MHz UHF radios and supports Satel 9600 baud with FEC ON or OFF the iGR will probably work great.
Repeater operation probably won't be dependable with 4800 baud protocols.
 

18. Waterproof? Suitable for outdoor use?

Yes, the iGR can be hung on a tripod in the rain for extended periods.
 

19. Is free shipping included?

No.
 

20. Does iGage supply or recommend a specific battery?

iGage will not supply batteries. Purchase locally or on Amazon.
The User Manual has pages of suggestions on how to choose an appropriate battery.
