Ultimate portable 800MHz antenna shoot-out!

Alrighty.........I want to do an ultimate 800MHz scanner antenna shoot-out. I have a Uniden 396XT and 436HP for testing, and the following antennas with or without adapters for trials.



1: Radio Shack 800MHz 5/8 wave whip

2: SpectrumForce 2db 7-800MHz 5/8 wave whip

3: ScannerMaster 800MHz dipole

4: ScannerMaster 800MHz 1/4 wave spike

5: Motorola 800MHz 5/8 wave whip

6: Motorola 800MHz 1/4 wave spike

7: Motorola 800MHz dipole



The RS800 has a BNC, the Motorolas have SMA-F, and the rest are standard Uniden SMA-M. Appropriate adaptors are attached to each scanner. I don't know of any other portable 800MHz antennas (popular) to test, so this is what I have available.



Now, for the testing. How best to do this? I was thinking a distant 800MHz control channel, and use FreeScan's logging signal strength numbers averaged, or the virtual control screens green signal meter. Would like to be able to produce some usable figures, and not measure a wavering fluctuating simulcast frequency, to keep the measurements as relative as possible.



BTW, the SpectrumForce 7-800MHz whips are currently under $8 at ScannerMaster currently.
