coax for hp 2

Can anyone recommend coax for the Home patrol 2.

I want to put my antenna, outside of my house, for better reception.

Thanks

LMR-400 ...

How long of a cable run would you need to get from the antenna to the scanner?

What frequencies are used by the systems you monitor?

About 15 yards.

The Mississippi Wireless Informatiion Network. 700.00 MHz-800.00 MHz.
And some of the local frequencies, 45.22-45.52-155.940-45.14-154.995-151.040 .

And where would I order the coax?


Thanks

Is it the the original antenna that comes with the scanner that you would like to put outside?
You have to waterproof it somehow and put in on a groundplane.

No it is not the original antenna--it is an expandable antenna to about 2 feet.

OK, so 45 feet.
On the 45.xx, 15x.xxx frequencies, you probably won't have much issue with just about any good coax.
At 700-800MHz, coaxial losses become a thing.
LMR-400 would be good, but RG-6 would be cheaper, easier to work with and easier to route. Picking up a pre-terminated 50 foot length of RG-6 isn't going to be hard. A good hardware store or home electronics store will likely have that.

The trick is the connectors. The RG-6 from a hardware/electronics store is going to have F connectors on it. You'll need SMA male on the radio end and whatever to match the antenna.

Waterproofing the connections outside -IS- important if you want this to last through any sort of weather.

LMR400 is going to be more costly, probably have minimal benefit over RG-6, and going to be stiffer, larger and harder to work with. Connecting heavier cable like LMR-400 directly to your scanner will put a lot of strain on the antenna connector, so add in a short jumper for more flexible cable to make the transition.

You will want an antenna designed for outdoor use, rather than cobbling together a mount for the factory antenna. A discone antenna is a good choice for receiving the wide range of frequencies you need to hear.

Yeah, I agree with Jon, don't use that outdoors.
Get a purpose built outdoor antenna. The one that comes with the radio likely won't last long mounted outside.
