FEATURES

External Sound: It's a common question... "What can I use to get better sound out of my radio equipment?" Two-way radios and scanners have never had great audio. But with today's products being made smaller and smaller, the audio is worse than ever. If your radio will be stationary, hooking it up to external speakers is the way to go. Many people opt for a single speaker, made by the radio manufacturers themselves. For home or office use, that's not really the best option. Those speakers were primarily designed to be stuck in a vehicle. They will work, but there's something a lot better... Send your radio audio through a set of properly designed, powered speakers. Yes, the audio you're listening to is in mono... But having two speakers gives better coverage, and you can also use them with your computer as well... or even a music source. Properly designed speakers will sound a lot better than just a little plastic box with a cheap speaker shoved in it. You'll be surprised at how conversations can often be much more intelligible, through improved audio.

Design: Since the speakers are powered, you don't have to be bothered with using a separate amp. Power and the audio source goes to the left speaker, which serves as the main controller, and then a cable sends the right channel audio to the right speaker. There's three different inputs on the speakers. A single 1/8" Stereo input on the front, and a set of RCA and 1/4" individual inputs on the back. There's also an optional bass boost circuit that can be switched on and off, if you prefer having deeper bass.

Accessories Included: Everything you should need to connect one radio/scanner, or a computer.

  • 1x 5' Cable to connect the two speakers together.
  • 1x 2' Cable with stereo 1/8" male connectors, for connecting a device to the front 1/8" input.
  • 1x 5' Cable with male RCA connectors on one end, and a single stereo 1/8" male connector at the other end. (This would be the cable to connect a radio.

It was not included by the manufacturer, but we ourselves also include a 1/8" stereo to 1/8" mono adapter, to connect your mono radio or scanner, using the 5' cable. All of this should be everything you need for connecting one radio. Alternatively, you could connect the speakers to your computer, and then connect your radio to the mic/line input on your computer. Purchasing a separate small mixer, you could send the audio from numerous devices into the speakers.

CoaxWrap - Non-Adhesive Silicone Cable Wrapping Tape (10 Feet)

CoaxWrap #1
CoaxWrap #2 CoaxWrap #3 CoaxWrap #4

SPECS

Type: Silicone Tape Stretching Ability: 300%
Adhesive: None UV Resistant: Yes
Length: 10 Feet Cold Brittle Point: -85 F
Max Temperature: 500 F Tear Strength Min: 85 PPI
Min Temperature: Flexible to -60 F Shelf Life: 60 Months

FEATURES

Design: CoaxWrap Silicone Tape is a super flexible tape that does not have any glue or adhesive... it simply sticks to itself. CoaxWrap insulates up to 8000 Volts, will not melt up to 500F (260C), and resists UV damage and weathering. The characteristics of CoaxWrap make it excellent for wrapping cable, connections and wire, to create an air and water tight seal. If CoaxWrap needs to be removed, theres no sticky residue or gooey mess left to clean up. The ten feet length included, should be enough to cover four average connections.

Instructions: Please follow these instructions for best results.

  • 1. Clean surface to be wrapped. Cut off length to be used.
  • 2. Peel back a short length of protective film. Keep tape clean and dry.
  • 3. Begin with one complete overlap of tape onto itself. (If this is for a cable connection that will be outdoors and positioned vertically, start wrapping from the bottom, and go up. This lowers the chance of water seeping into the seams.)
  • 4. Stretch CoaxWrap while continuing to wrap object with half-laps, removing clear film as you go. For greater pressure resistance, use 2 or more tightly wrapped layers.
  • 5. End of tape at final wrap should be completely positioned onto itself. CoaxWraps bond begins to cure immediately upon contact with itself. Repositioning or removal is not recommended after 2 minutes of wrapping. CoaxWrap will form a permanent, cohesive bond within 24 hours at room temperature... faster if heat cured at up to 350F.

Cables

Below you will find a large variety of RG8X cables that we offer. Due to the almost infinite number of cable/connector variations, we can't list everything. If you don't see what you need, please email us and we'll see what we can do. If you have basic questions about antennas or cable, please try checking the FAQ page. If you're confused about connector types, the Connector Guide may help.

Choose Cable Length

Clicking on one of the cable lengths to the left, will take you down to that section on the page. Each length box has two drop-down menus where you can choose your connectors. Note: Options that offer 'F' Female are achieved with an included 'F' Female/BNC Female adapter. Options that offer MCX Male are achieved with an included MCX Male/SMA Female adapter. Because of this, each of those options are an additional $5.00. It is necessary to do this, due to the fact that neither 'F' nor MCX connectors are available to fit on standard 50 Ohm cables.


4 Foot RG8X Flexible Cables

These are a great flexible patch to be used between a large main cable and your device, if attaching your main large cable directly would be difficult. They're also good for adapting various devices. Signal loss is not an issue at this length. Please choose your connectors carefully.

Connector Guide

N
N Male Connector
Male
N Female Connector
Female

This is the most common connector used in proper interior/exterior communication applications. They're more water resistant than UHF connectors in the clamp versions, and they also handle higher frequencies better. They come in both crimp and clamp form, clamp being the more water resistant, crimp being attached to the cable in a stronger fashion.

UHF
Male UHF (PL259) Connector
Male
Female UHF (SO239) Connector
Female
The UHF connector is the most common connector found on consumer grade equipment for both interior and exterior, but it's not the best connector to use. It can usually handle higher power than N connectors can, but it's much worse at handling higher frequencies, and is less water resistant. The UHF connector became a tradition by default because of it's age... which makes them cheap, and that's why they continue to be used. The Male UHF is technically referred to as a PL259 and the Female is referred to as an SO239.
BNC
Male BNC Connector
Male
Female BNC Connector
Female
BNC is probably the most popular quick -disconnect type of connectors used for interior applications. They're referred to as Male or Female. BNC is found on most scanners and many handheld ham radios. They're primarily used for indoor applications. They also make good connectors for patch cables.
TNC
Male TNC Connector
Male
Female TNC Connector
Female
The TNC connector isn't terribly popular, but it does get used once in a while. TNC connectors are basically a threaded version of the BNC. They also work better at higher frequencies, making them good for patch cables used in critical applications. Typically they would be seen on more commercial grade equipment.
Mini UHF
Male Mini UHF Connector
Male
Female Mini UHF Connector
Female
Mini UHF connectors are exactly what the name implies... a smaller version of the large UHF connector. Mini UHF connectors occasionally show up on equipment, but aren't used much. Like the larger version, they aren't very good with high frequencies.
SMA
Male SMA Connector
Male
Female SMA Connector
Female
SMA stands for: "Sub Miniature Version A". The SMA connector is the most diverse and sometimes confusing connector there is. The SMA was created for applications where space on the device is an issue. The SMA has good performance but is very small, which can often make it a physically weak connection. You wouldn't want to use SMA unless a device dictates it. What makes it confusing is how manufactures use it... Typically it will be used on small handheld devices. Sometimes they will use a 'Reverse Polarity' version, where the outer chassis or inner pin sex is reversed. Also, manufacturers will sometimes put the Female version on the radio and other times the Male version... This sometimes comes down to the design, but they also do it to try and create a proprietary connection so you'll have to buy their own antennas and accessories.
Motorola
Male Motorola Connector
Male
Motorola connectors aren't really used on scanners or consumer equipment much anymore, but they use to be used on older equipment, including scanners. These connectors kind of look like an RCA audio connector, like you see on TVs and stereos. Adapters can often be found to use them with BNC connectors.
F
Male F Connector
Male
Female F Connector
Female
F connectors are primarily for 75 Ohm video applications, and should not be used in radio applications if possible. That said, there are some manufacturers that offer RG6 cable and F connectors with their antennas. This is mainly done because RG6 cable is cheap and plentiful. The only semi-proper way to go from 'F' to other 50 Ohm cables, is to use an adapter.
MCX
Male MCX Connector
Male
Female MCX Connector
Female
MCX connectors are primarily for 75 Ohm video applications, and should not be used in radio applications, if possible. However, there are some manufacturers that have used this type of connector on their devices for some reason, most likely because they are one of the smallest available. For example, some ADS USB devices utilize this connector. The only semi-proper way to go between MCX and other 50 Ohm cables, is to use an adapter.
Reverse
Polarity
Male BNC Reverse Polarity Connector
BNC Male RP
Female SMA Reverse Polarity Connector
SMA Female RP
Male TNC Reverse Polarity Connector
TNC Male RP
In rare instances you might run into a version of a connector that is referred to as "Reverse Polarity". These connectors will either have outer threads that are the reverse of what would normally be used on the same connector, or inner pins that are the opposite sex of what would normally be used on the same connector. Notice in the photos above how each pin is actually the opposite of what would normally be used. These have started popping up more and more, mainly because the FCC believes this will hinder people from using illegal external antennas that are not supposed to be used on certain equipment. But you can also find reverse polarity connectors on some equipment from manufacturers who are trying to get people to buy their own antennas.
