I am designing a piece of equipment that requires the mounting of the following items/antennae in close proximity (within a 15cm radius) ideally on the same horizontal plane:
1. a satellite terminal (about 10cms diameter)
2. a GPS transceiver (1500MHz and about 5cms diameter)
3. a GSM modem whip antenna (900MHz or 1800MHz)
4. a radio whip antenna (2.4GHz)
Operational combinations will be: SAT+GPS, GSM+GPS, and Radio + GPS, with the other items switched off, but the antennae remaining in place.
Will the operational items be affected by the unused antennae, reducing polar response and creating blind-spots?
Are there multi-function antennae available (eg, GSM+radio) that offer the same performance as if separate items?
I'd appreciate your expert opinions on how to position each of these items and maximise the performance of each. Many thanks in advance.
