Sorry, it is not possible. The markers do NOT select the band. They are simply markers for manufacturing. The other IC amplifiers and filters on the board would need to be changed out to make it a wide band amplifier.

The difference between the two UHF amps is the frequency range for which they are designed. The ua870a was designed for a smaller frequency range mainly to prvide additiona coverage area for teh Shure UA series of wireless systems. The WB variant is designed to allow for use for Shure's entire UHF wireless line including: (UA,UB, J4,J5,L2,L3, H3,H4, and M4). It is not possible for the 870A to cover the full spectrum like the WB.

The ua870a frequency range is between 782 810 Mhz, while ua870wb is between 470 and 900. Yuo must set both on a common value.

Here is the reference manual

    There seem to be a little confusion.The frequency band cannot be ' 662-698mhz' , that is a range. The frequency band is unique for each setting.

    For the rest you cannot "transforme ua870a the reception to ua870wb", as the ua870wb has a different range. UA870A range is much smaller than UA870WB
    All you can do is use UA870A within a range covered by UA870WB .




    UA870A . . . . . . . . . . . . . . . . . . . . . . . 782-810 MHz
    UA870WB . . . . . . . . . . . . . . . . . . . . . 470-900 MHz

    If you give me the whole description of the problem you having with your areal (eg, I want connect to this device , it does not work because of this and that), probably we can find a solution that makes som sense.
    As it is now your request sounds like: "how do I fit 10 gallons of water in a 5 gallons tank?"

    Regards

    To make it easier: you cannot get 662-698mhz on a UA870A because UA870A range starts from 782 mhz. How do you get a violin playing double bass notes?

Behringer Powerplay Pro-8 HA8000


Most behringer transformers are 18Volts 1-2 amps to my knowledge, specially in the smaller units. If you are not sure start with reconnecting a 12 volt (AC) external supply and see how you go. Behringer uses (indicated) 17Volts transformers but that is neither here nor there. Good Luck.

I have a new hdtv antenna and my hdtv gets all the local channels except 8. The direction from my house is 171 and that is also channel 4. I get 4 fine but not 8. what's up?


hello,
There would be weak signal reception at your antenna so it can't get the other channel. So change the antenna direction. If there's no result then increase your antennas hieght means keep your antenna at higher position.

I moved and cant figure out how to hook my 4030 channel master antenna up again. I have a converter box and hd toshiba tv


INSTALLATION

Channel Master by PCT indoor antennas are designed to provide optimum reception of

UHF / VHF and FM signals. These antennas have 75 ohm outputs, which allow simple,

hassle-free connections to today's newer TV sets that have 75 ohm F type connector

inputs.

Simply attach one end of the supplied 6' cable with F connectors to the output of the

antenna (Fig.1). Attach the other end of the cable to the input of the TV set or VCR

(Fig. 2). Some adjustment of the antenna might be necessary for optimum viewing.

Model CM-4030 includes a built-in amplifier and separate power supply.

1. Follow the same steps as above for antenna to TV / VCR hookup. Note : Model

CM-4030 also allows for two set / VCR hookups with its unique dual output feature.

2. Insert the power injector into the back of the antenna (Fig. 3). Plug in the power
transformer to the closest electrical outlet (Fig. 4).

Coaxial FM antenna


Radio Shack has an
adapter catalog number 278-0291. It takes some effort to push the 278-0291
adapter onto the FM UNBL 75 ohm terminal so wait until you have the 278-0291
installed before you connect your 75 ohm coax on to your new adapter.

This will resolve your FM screw on F connector antenna interface issue.


I see others trying to
help suggest using a 300 ohm to 75 ohm transformer match unit, this isn't what is needed. Your receiver antenna input IS a 75
ohm input.

Am fm reception bad


FM reception is weak



What to do


• Extend the power cord as much as possible. The FM antenna is in the power cord.


• Move the power cord to adjust the FM antenna

• If you still have problems with FM reception, you may need an external antenna.


* Call Bose®Customer Service to request one.


The external antenna on your radio is a coax (round) design It needs an adaptor and an antenna which are cheap.


Easy to make, radio shack "F" connector 90 degrees or straight, to 300 ohm wire connections. Attatch a 300 ohm flat ribbon antenna cable to those two screws and plug into radio and see how your reception is. You will need to position the antenna wires to get best reception. I have hid them in back of paintings and so on.


Cheapest solution next to putting an extension cord on radio power cord.

Improve reception


HI there,

Well Yes you can improve the reception, please follow the below steps -

Improve FM Radio Reception -
 
1. If you don't have an antenna connected to your FM receiver, purchase a simple dipole antenna--a simple T-shape flexible wire-- and connect it to the FM antenna inputs on the receiver. Because FM signals are directional, you'll want to experiment with the positioning of the wire to find the best reception of the station you're trying to receive.
 
2. If you're still not getting a good signal, try an indoor amplified antenna, which you'll find at an electronics store. Don't buy one unless you get a guarantee that you can return it for full credit if it doesn't solve your reception problems.
 
3. If your signal is weak because you live a long way from the transmitter, install an outside antenna and mount it as high as is practical. If you're primarily interested in getting signals from one station or from a group of stations in one direction, get a directional antenna and point it toward the transmitters.
 
4. If you're using a portable FM radio where the only antenna is the power cord, stretch the cord as straight as possible and experiment with positioning again.
 
5. Temporarily switch to monaural mode to improve a weak signal on an FM receiver.


Improve AM Reception -
 
1. Gradually rotate the radio 360 degrees. Leave it in the position where it sounds best.
 
2. Reverse the AC plug if it isn't polarized. (If you can flip the plug over, then it's non-polarized.)
 
3. Plug the radio into a different AC outlet.
 
4. Move the radio closer to a window.
 
5. Experiment to learn if appliances and powered products in your home are causing interference: computer monitor, television, electric blanket, light dimmer, fluorescent light, hair dryer, air conditioner, smoke detector. If possible, turn off the offending item. Otherwise, move the radio to another room.
 
6. Upgrade to an external antenna if your receiver, tuner or radio has a place to connect one.
 
7. Buy a passive AM antenna that doesn't need to be connected to a radio or receiver.

Good Luck!!

Thanks

Fm Radio signal?


There was a black wire included (with a metal "cap" to insert in the FM center connector) that served as the FM antenna, but in a pinch any wire can do, preferably about 33" long and with the insulation stripped from the last inch or so (or get creative and sand the last inch of varnish off a properly sized untwisted clothes hanger and gently bend to suit). Bare stranded wire should be twisted or folded until it's thick enough to firmly fit the middle "hole" of the FM antenna connector. Be careful that no strands of wire short to the metal ground "ring" surrounding the hole or the antenna won't work (although it won't burn out your amp like shorting the speaker wires would, it just won't work). Orient the wire horizontally or vertically for best reception. This unit also doesn't pick up FM very well if you're in a steel-framed building or away from windows in the general direction of the local transmitters, so moving the unit closer to a window may help dramatically. In bad reception areas you can get an external FM "rabbit ears" type antenna but you'll need the "European" style of 300 ohm to 75 ohm transformer to plug it into the unit's FM connector (one that has a bigger central connector "plug" than the usual US units). Some cable systems also still support FM, if yours does, a VHF/UHF/FM signal splitter and either the above mentioned transformer attached to flat 300 ohm cable or a plain  "European" style connector attached to the end of the 75 ohm round black cable will do the trick. Some Radio Shacks have them. Good luck!
