Default G5 Antenna Comparison

With all the talk about the G5 stubby antenna and its performance I wanted to do a comparison.

I compared the G5 stock antenna with a Unication U3 and a Motorola APX. Both the Motorola and the Unication U3 are 7/800 MHz antennas. I am not saying either are the best, they are just what I have at my desk to test.

Diagnostics can be enabled from the PPS in D 6. You will get a screen with similar info.

Here is what I got.

G5 with stock antenna -108
G5 without any antenna -131
G5 with Unication U3 antenna -98
G5 with Motorola APX antenna - 102

On the radio or while looking at it on your monitor?

On the radio, you can't.
On your monitor, Crtl +

The diagnostic display looks quite different on my Phase-II G5 - it has four pages. Also, the RSSI doesn't seem to be real-time (it doesn't vary).

That is an engineering mode. Your option for RSSI is the one you are seeing on the menu.

The RSSI meter pegs out at "> -100" so it becomes hard to quantify antenna performance at my location. Is there any way to change that to get the actual values?

The diagnostics screen is designed to aid in trouble shooting RF. At signal strength over -100 there is no need. Unfortunately that is how it was designed.

Unication U3 antenna? I don't see it listed anywhere for sale. What does it look like top to bottom?

Damn. The more I look at Unication, the more I like. I remember the Motorola Flex and Alpha pagers years ago that were actually Unication built with Moto badging.

That being said...after following your link I discovered the U3. I have a few questions.

1. How does one get a U3?
2. How much?
3. Only for non-North America markets?
4. How have we not heard about this?
5. Jeezus, this thing appears to be a game changer. Is non-affilate rx only scan a thing on this unit? (The Relm/BK units possess this, but pricing is just above most hobbiests' budget)
6. Why the heck are we fooling around with consumer-grade stuff when this thing exists?

The issue is see with most P25 equipment is pricing geared toward agencies who qualify for grant $. Does this unit follow this trend? (don't blame Unication if it does, who would leave cash on the table?)
