Antenna Jacks

Some wireless cards have an antenna jack, for plugging in an external antenna to boost your signal.

The internal antennas have good range, up to about 300 feet for Orinoco cards (depending on whether you have direct line of sight to the Wireless Access Point, in which case the range may be  two miles (3 kilometers), approximately.

If the distance to the Wireless Access Point’s antenna is more

than 300 feet, you should consider getting a card with an

antenna jack, and also get an external antenna. Without an external

antenna, you may have issues with the signal fading out sometimes.

Protect your Jack & Connector

MC is the standard type of antenna jack of Orinoco cards and all related cards, co-branded cards, etc.   MMCX is the standard type of antenna jack of Senao, Engenius, Ubiquiti and Cisco cards as well as a few other brands.  RP-MMCX is the jack of Zcomax, SMC and a few other brands

MC and MMCX jacks and connectors are very small, therefore

Vulnerable to damage unless properly protected.

ADVANTAGES of RP-SMA CONNECTOR vs. MC & MMCX:
The connector is about 5x larger in diameter (10mm vs. 2mm),

and is a threaded connection.  Advantages:

1.  Extension cables can be used as needed, so that the

Cable length fits the need in any particular situation.

2.  It has much higher resiliency against wear.

MC & MMCX connectors will actually break after a lot of plugging in,

pulling out, and the strain from the cable being tugged in day

to day use.

3. Less loss of gain with the RP-SMA because of the

threaded connection and the lack of wear.  The RP-SMA

antenna/adapter-solution  will maintain it’s functional integrity

much better and over a very long period of time, compared

to the antennas that simply have an MC connection.

ADAPTERS TO RPSMA:

These adapters for MC or MMCX can be semi-permanently bonded to the

card, reducing stress on the fragile MC/MMCX connector, so that you

can remove & reattach the antenna as often as you wish without causing

damage to the fragile connector.

The MC or MMCX end can be permanently bonded to the jack

(using silicon cement) or semi-permanently (using velcro).  The adapter

thereby provides a second, more durable antenna connector (RP-SMA) with

the capability to add/remove the external antenna with a screw on/off

connector, rather than using the (much smaller) plug-in/out

connector (MC) that is susceptible to damage over time.

Velcro strips and “coins”  cut to perfectly fit your card, and

hold the MC or MMCX connector and jack together, so that movement, wear and tear will be significantly reduced.

ANTENNA JACK INSTRUCTIONS FOR PCMCIA / CARDBUS

The antenna jack is at the end of the card that sticks out from the laptop/notebook.  It is covered by a small, round plastic cover (twice the size of a pin head).  The small plastic cover must be removed to expose and use the jack.  It can be removed with a small, sharp object, such as a needle.

Below:  The adapter solution: MC to RP-SMA, mounted to a card with velcro pieces.  On the right is a pigtail (antenna lead or extension cable) with RP-SMA (male) connector, connected to the threaded RP-SMA (female) connector of the adapter:

Pigtail / adapter:

Enables you to attach any of the antennas in our eBay store that have an RP-SMA(male) connector or a N(female) connector.

Extend range by attaching a well-positioned, long-range antenna:  Antenna options are within the listing for this adapter.

Another solution (photo at right):  To add an external antenna and increase gain: Our USB clients with an RP-SMA connector: In this case, you would disable your internal wireless card and use the USB client, attaching an external antenna with RP-SMA(male) connector.

CABLES – GENERAL INFORMATION

It is best to have the shortest cable that will serve your needs, since some

signal strength is lost in the antenna cable.

Signal loss per meter:

LMR100A cable:  1.28dBi of loss/meter

LMR200 cable:    0.54dBi of loss/meter

Antenna cables in our store have cable type equivalent to LMR100A

or higher, in quality and signal-loss per meter.  Most of our cables of 2-meters or more are

made from cable equivalent to LMR200 in quality and signal-loss per meter.  The higher

quality of the cable of our cables translates into lower sigal loss / better performance.

RG174 cable (which you may see in competitor’s offerings) is much lower in quality than

the thinnest cables that we use for 1-meter-cables and shorter (LMR100A-equivalent).

COMPATIBILITY

RP-SMA connector fits items that have a (female) RP-SMA (Reverse Polarity [RP] SMA) jack/connector. RP-SMA = Reverse Polarity SMA

SMA connector fits items that have a (female) SMA jack/connector. Gender of SMA refers to the pins inside–not the threads:  SMA male has threads on inside

MAGNETIC BASE FOR DIPOLE / OMNI ANTENNAS

Fits antennas with RP-SMA male connector

PIGTAIL to RP-SMA(m) connector: Has 1.5 meter cable (5 ft)

Magnetic Mount antenna base very firmly attaches to metal surface – at a height or

Position where it can pick up more access points.

Base-top has an RP-SMA female connector, which fits 9dbi dipole/omni antennas such as the one pictured at the right side of this page:

The RP-SMA gender refers to the pins inside–not the threads.  RP-SMA female has threads on outside.

The end of the 1.5-meter pigtail-cable has an RP-SMA(male) connector.   Cable is a low-loss, very flexible cable (loss-per-meter is equivalent to LMR100A). Most PCI wireless cards (for desktop PCs) have an RP-SMA female jack.

COMPATIBILITY AND GENDER DETERMINATION

Connector on the base fits antennas that have a male  RP-SMA (Reverse Polarity [RP] SMA) jack/connector.

Connector on the pigtail fits items that have a female  RP-SMA (Reverse Polarity [RP] SMA) jack/connector. RP-SMA = Reverse Polarity

antenna cables with RP-SMA (male) connectors.  Expand your coverage or reception area by having two antennas instead of one!

RP-SMA GENDER IS COUNTER-INTUITIVE in two ways:

Please observe picture & note it is correct.  (1) The gender is referring to the pins inside–not the threads.  RP-SMA male has threads on inside.   (2) “RP” stands for reverse polarization – the pins are female when they appear to be male, and vice versa.

Reverse polarization:  “RP”

Connectors with “RP” in the name are further complicated by the “reverse polarization” (RP):

The pins are female when they appear to be male, and vice versa.

If the documentation refers to the connector as “reverse ____”:

This is the same as RP-____ (e.g,  “reverse SMA” = RP-SMA)

A Note About Reverse Polarity (RP) / Reverse Gender Connectors And Adapters
Reverse Polarity/Reverse Gender connectors satisfy FCC Regulation 15 by switching dielectrics and pins/contacts between genders. For example, a Reverse Gender Male consists of a male body, however, the dielectric and contact are female. Basically, an RP female will look like a standard male, and an RP male will look like a standard female. Reverse Polarity connectors and adapters will not mate with standard coaxial connectors. To attempt to do so will damage the connector.

    I have a Buffalo airstation wli-cb-g54A card and a flat 18dB antenna that is N-female (external thread). I need a cable 2-5 feet long and wonder if you have it. I believe the airstation has an MC connector, but I am not sure, and then the cable would need an N-male on one end.

    Can you help?
