aerials

You can just about get SMS emergency coverage with the latest generation of modems and aerials designed for the purpose.

Disclaimer: not an active HAM, used to clean seagull crap off 500KHz distress aerials on small ships in the last century.

The UHF aerials you buy today last a couple of years before the plastic bits go brittle and they fall apart.

Some of the prototype designs for the aerials are currently being made by a bloke called Pete, in the room next to me.

If there's no tone the two signals are exactly in phase - the two aerials are exactly the same distance from the transmitter.

They are turning Android devices into wireless meshes and have been sending up balloons with device + high gain aerials for quite a while...

Show me a military that's cool with open aerials of their bases.

You can kind of do that quite easily at low frequencies, by measuring the phase of signals coming in from a pair of aerials.

But over here in the drier and less windy north-east, there are still combination Band I/III aerials on a lot of houses.

Then we had an aerial manufacturer who kept shipping us different aerials every time we ordered the same part, which never matched the sample.

I don't think it's impossible cloudless aerials were inspired by MapBox though...

Bugs have antennae, radios have antennas (or aerials).

If you look on some police cars you'll see a group of four aerials about 15cm apart stuck to the roof which used to be used for "Lojack" style trackers.

Where I grew up in the north-west of Scotland it was pretty much only ever UHF - salt spray and 140mph winds tended to take out the long dangly "Band I" VHF aerials for 50MHz-ish.

But if someone says "a 100 Mhz signal" you can guess that they don't mean the signal is allowed to cover 70 Mhz to 130 Mhz (60 Mhz of bandwidth), because: a) that's a ~2x range in frequency, which make it hard to design appropriate aerials, filters, modulators, etc; b) that isn't how spectrum is actually allocated anywhere I know of.

Aerials won't get better 'the more peopl euse it'.

Or a screen saver inspired on Apple’s Aerials.

I'm pretty sure I do this on my mac using Aerials.
