It is fairly new, its a Bearcat BCD996T not the newest XT version but it has the digital,

 It almost sounds like pager data but just flat square wave sound, and goes away when they un-key, I can turn off the squelch and when the person un-keys its normal static, so Whatever it is, i wonder if its some way form of encryption or they are carrying someone else's signal further. I will see if I can get a short clip of it

 I listen to my police scanner now and then and lately i hear what sounds like pager data or square wave sounds over the people talking, you can make it out as if its mixed in, what could this possibly be?

One thing I have noticed on this antenna, which I was always under the impression does not happen on 5/8 wave is the picket fence affect on reception.

 I also have a thought that this maybe due to my temp mag mount until my nmo mount arrives

I should also state this is a mobile antenna,
http://lairdtech.thomasnet.com/viewitems/vehicular-mobile-radio-antennas/wideband-antennas

 I have a Laird/Antenex CW4405C Wideband UHF Antenna. Some sites say 5/8 over 5/8 but im lost on what this really is, I have never heard of a 5/8 over 5/8 or closed collinear antenna.

 does this mean this antenna is ground plane independent, Is this a good or bad design vs a normal 5/ wave.

 Any ideas anyone?

Our system is vertex units on the business band frequencies, we are in a manufacturing plant that has many large metal scaffolding and has the aluminum foil roof barrier. Signal is faint unless one person goes out side. Windows are not possible as our manufacturing and our shipping portions do not have them or the option to walk away to do so. one building has one radio the second has 10 radios. So we can say the one radio is a dispatch for manufacturing. If i go on the roof of our building the person at dispatch can hear me inside his building no matter where he is. So the signal is there to grab just both being in the building we are being limited. So I am thinking if dispatch had a small 3 element yagi we maybe fine.

  Before we spend the money my question is, will a yagi allow us to pick up a distant hand held that's inside a building that's about 2 miles away?

 We have an issue between building to building communications, I was suggestion a yagi at one station to allow easier contact. Now I know yagis are great and have great gain, We just wish to make building to building on UHF easier, if one person gets on the roof of the other building contact is 100% I just want others inputs before spending the money.

 Any ideas?

Price?

 Actually I have not gone that far as I said the MFJ was not to far off from the SWR meter so i didn't sweat it. I think the only time I have never seen an SWR Meter move was on my 1/4 wave CB Antenna, "and I got tired of the up and down adjustments" Not saying a 1.1:1 is impossible on my current 1/4 wave and if my meter says 1.2 or 1.3 I am not gonna cry.

 Btw I did purchase 210 10Kohm 1W 5% Carbon film resistors to make a nice little dummy load.  

 Just some .02c I have the SWR Analyzer from MFJ-269 and nothing will read below 1.3-1.5 1/4 or even 5/8 wave.

 Now a Diamond SWR meter reads 1.2 so it appears thats the best the analyzer can do maybe.

Funny this guy is now asking 600$ and still posted,

 btw yes all mode, I ask cause as you start going up in price they drop 2m and 70cm rigs that cost up to 10k and im thinking well if there packed with all the best features why drop it. just trying to figure it out.

I mean that for someone that is just starting out.. sorry.

Sorry my mistake earlier, Yes 6m/50mhz is VHF

 But on the 857 its not really free, I bet if they excluded the 160-12 meter you could get a better rig for vhf and up. Yeah maybe 10 meter would be nice as well but.. I'm talking for the guys who only have a tech license. anything down on HF is almost useless unless you do CW

 If you look at units that are 160-12m they are packed full of features but as you add more frequency coverage they have to trade off somewhere to keep the bill down.

 Also as stated by KI4SDY 50watts on all bands even UHF would be nice not these 20 watt units.

 Think of this a nice base or base/mobile unit with 50mhz 144mhz and 440mhz, Since tech license is the first step once obtaining your ham license.

 Btw yes I know 6m is HF I'm talking below 6m when I say no HF
