Scanner Tip: Indoor Antennas

Chances are, if you have a scanner in the house, you have wondered if you need an outside antenna. While an outside antenna will almost always work better than an indoor antenna, sometimes that just isn’t feasible. If you live in a rental property, apartment or condo, or in an HOA restricted area you may not be able or allowed to install an outside antenna. Sometimes you just don’t want to go thru the work to do it. Maybe the spouse or significant other just won’t allow it.

There are alternatives, but as they are also compromises, they may work as well. They may however be good enough to allow you to listen to your targets. Depending on your unique situation, some or all of these ideas may or not work for you. Remember: There is never a guarantee that any of these ideas will ensure that you will be able to monitor your targets.

Let’s start with the simple ideas first. Your new scanner comes with a back of the set (or side of the set for a Home Patrol) antenna. This is usually a metal telescoping rod or a rubber-duck style antenna. Sometimes better reception may be had by a simple relocation or tilting the existing antenna. Maybe move the radio with its antenna closer to a window or away from the large metal objects will help.

The next step would be a better BOS (Back Of Set) antenna. ScannerMaster sells a variety of antennas, from direct replacements (if you lost or broke the one that came with the radio) as well as more advanced antennas. If you mostly monitor 700/800 MHz. systems a specialized antenna for these bands will work better than a general use antenna.

If these don’t help, then you may need a remote inside antenna like the Nomad. The Nomad is a wire antenna and is amplified (active). This allows you to mount the antenna in a better location and leave the radio where you want it.

The next step might be using a base station antenna indoors. ScannerMaster has several of these types. Basically this means a base station antenna with some sort of base to support it along with appropriate coax and connectors. These can be set up on a balcony or behind the drapes for aesthetic purposes.

You can also try a mobile antenna adapted to home use. Try a magnet mount antenna on top of a large metal cabinet, window air conditioner or balcony railing. Window mount antennas can be mounted on an apartment window just like you would on a car. Suction cup mounts work in a home just as well as in a car.

If you have access to an attic then you might try putting a base station antenna there. Try to stay away from large metal objects. If you have metallic shingle liners or solar panels they would likely interfere with your reception.

If you install an antenna outside, either on the roof or a tower, make sure to properly ground the installation to protect from lightening and watch out for electrical wires! Consider having them professionally installed. Use a high quality coax. Usually thicker cables work better at higher frequencies and longer distances. 50 or 75-ohm cable is fine for scanners since you will not be transmitting thru them. We will have a blog post soon all about Coax!

New Product – New 700/800MHz Base Antenna

762-894 MHz 5dB Panorama Elevated Omni Antenna Having a hard time receiving trunked and digital 700 and 800 MHz systems?

The new “762-894 MHz 5dB Panorama Elevated Omni Antenna” is a great tuned omnidirectional antenna. This antenna can be used for temporary field use or permanent installations. Flexible helical elements are used to provide an effective but compact ground plane. The center fitting has a metal body to carry the radials and a moulded insulator for the radiator. The whip element is plastic coated for weather proofing and durability. The antenna is only 15″ tall and 4 1/2″ in diameter but with its 5 db of gain it does an outstanding job receiving 700/800 MHz systems and interestingly it does an excellent job of also receiving 400-500 MHz channels as well. A great find. – Order Now

Scanner 101 – Tips on picking and installing a Roof Top Antenna

Have you been putting off installing a roof top antenna for your scanner? A roof top antenna is the best way to increase your scanner’s range.

What antenna should you pick?
When selecting you should keep the following in mind:
What type of communication systems are you monitor? VHF, UHF and 700/800/900MHz so on… If the area is using the same type of communication system you may want to consider a single band antenna. If there is a mix I would recommend “wide band” antenna.

Mounting your antenna
When selecting antenna you want to keep in mind; how and where you’re going to mount it. So many options available from non-penetrating, tripod, and wall mount. Keep way from power lines and telephone/cable wires. The higher the better, be sure you clearing anything that would block signals such as chimes.

Coax Cable
Your antenna performance depends on great coax cable! We carry LMR-400 Coax cable which is a high-end low signal loss coax. When planning out your coax routes, be sure you have a little extra, but not too much. Shorter runs are always best. Keep this in mind: the old carpenter rule of thumb, measure twice, cut once!

Will you have multiple listening locations?
Depending on how many listening locations you have in mind, you will need a 4 Port or 8 Port Multicoupler. This should be placed somewhere in a central location in your home or office. I would recommend running LMR-400 Coax cable (no more than 100 feet) from the antenna to the Multicoupler. From the Multicoupler to the scanners I would recommend LMR-400 or RG-6 Coax (no more than 50 feet). Both of the multicouplers have a built in pre-amp to cut down on signal loss going to the monitoring locations.

Installing the antenna
If your pretty handy this can be something you can do on your own, with help from a friend. Just following instructions provided with the antenna. If heights are not you thing I would recommend hiring help.
