WiFI low profile permanent mount

New WiFi low profile permanent mount antenna

Specialist Antennas is now stocking a new WiFi low profile permanent mount antenna from Laird.  The TRAB2400/49003 is a black, robust, low profile dual band (2.4 and 5 GHz) WLAN antenna designed for mounting onto a metal surface such as a vehicle roof, cabinet or enclosure.

It mounts via a N-Female connector underneath and is held in place by a locking nut. We are stocking the version with the black radome. Please contact us if you require the white version.

Customers in Europe can purchase this antenna via our Connex webshop.

4G High Gain Omni Antenna

Hot Product – 4G High Gain Omni Antenna

The HGO-4G-LTE from Sirio Antenne in Italy is a 4G High Gain Omni Antenna intended for outdoor installations typically for wireless access applications. This antenna is encapsulated in UV-stabilised thermoplastic and comes with mounting clamps making it ideal for long-term outdoor deployments.

With a true gain of 5-6 dBi across the bands, the HGO-4G-LTE works well in delivering reception in areas of fringe signal coverage. As standard, we supply the antenna with either 0.5M or 5M of cable and a SMA-Male connector. Other cable length and connector configurations are possible. Through the use of a small pigtail cable, the antenna can also be presented with TS9 and CRC9 connectors which are very common in 4G LTE modems, USB sticks and dongles.

Our antennas from the Sirio range include the SMP-4G-LTE; a directional antenna with higher gain covering 4G and LTE bands. Or alternatively for radios requiring MIMO (multiple In multiple Out) functionality, SAS stocks the MIMO version of the SMP, the SMP-4G-MIMO.

All three antennas can be purchased via the Connex Webshop along with low loss jumper cables such as BWL195 or RF400.

A true 4G high gain omni antenna such as the HGO-4G-LTE is a key component when specifying 4G and LTE access installations. Be sure to verify the specification and the performance of the antenna you select as not all antennas are (or advertised specifications) always what they appear to be.

bi directional WLAN train antenna

PCTEL introduces bi directional WLAN train antenna

PCTEL has introduced a new bi directional WLAN train antenna, the PCT-RSABD-DP. This new antenna is a train roof mounted solution for 4.9 to 5.9 GHz. It is groundplane independent as a result it can be mounted on either metal or non-metal roofs or surfaces. This new antenna is built to survive high vibration environments therefore suitable for rail use.

This antenna has a stud underneath for mounting however we supply custom cabling separately.

Bi directional WLAN train antenna

The PCT-RSABD-DP features high port-to-port isolation and dual feed, dual slant ± 45°, linear polarization with symmetrical patterns, maintaining the same pattern performance over each polarization

The datasheet and product information can be found on the PCT-RSABD-DP product page.

RF coaxial cables compared

RF coaxial cables compared

SAS receives a fair number of calls and e-mails about the correct RF cable to use so we thought we would do a blog entry on RF coaxial cables compared. Such cables are used for VHF, UHF, Cellular (3G, 4G, and LTE), GNSS and WLAN applications. The connector choices are also varied.

In the image above you can see 5 RF  coaxial cables compared. From left to right they are as follows:

RG174 – 2.8mm overall diameter

BWL195 – 4.9mm overall diameter

RG58 – 4.9mm overall diameter

RF240 – 6.2mm overall diameter

RF400 – 10.3mm overall diameter

In simple terms, the thicker (or larger diameter) the cable, the better RF properties the cable has and less attenuation per metre meaning less loss across the cable run.

Looking at the cables above, RG174 is quite thin and flexible, but it is quite lossy. Typically with losses at around 98 dB/100m at 1000 MHz, you wouldn’t want to use RG174 for long cable runs.

BWL195 is a good cable with better electrical properties than its neighbour RG58 due to its solid copper core. RG58 is the same diameter as BWL195, but has a stranded core which affects attenuation per metre.

If you can work with BWL195, then maybe you should consider RF240. At just over 1mm larger in diameter, the RF240 coaxial cable has excellent RF properties and is still thin enough to be flexible and for cellular applications can typically be used in cable runs up to 15-20M. At 1000 MHz, the loss of RF240 is 26 dB/100M.

If RF240 is not sufficient and you want an even lower loss RF cable, the RF400 might be for you. At 10.3mm overall diameter it is not as flexible as BWL195 or RF240, but attenuation is even better making it suitable for longer cable runs.

For any of the above cables, Specialist Antennas’ sister company EAD builds custom cables to order with length and connector terminations configurable. In most cases, lead time for custom cables are 2-3 days unless uncommon connectors are specified. For more information and quotes, please contact us.

Website revamp for Specialist Antennas

SAS is pleased to introduce a website revamp for Specialist Antennas to showcase its full range of world-class antenna products. The new platform has easier to navigate categories and with improved information on products from our suppliers including Sirio, Laird, PCTEL, Smarteq and Scan.

The products on our site represent only a fraction of our portfolio of over 6000 products, so please contact us if you can’t see what you are looking for.

4G LTE multiband flexible PCB antenna

The L-Flex is a flexible 4G LTE PCB antenna

We are pleased to introduce its new L-Flex antenna, a flexible 4G LTE PCB antenna. Designed to be integrated into 4G LTE multiband terminals, devices and wireless products, the L-Flex is an innovative antenna solution for many applications. It can be deployed in such products as security and alarm panels, kiosks, wireless CCTV platforms and industrial telematics and monitoring where a groundplane independent antenna is required.

We are pleased to advise you that L-Flex has variety of coaxial cable and connector options which lend themselves to connect to variety of 4G and LTE modem, terminal and router platforms. The most common connectors are U.FL, TS9 and SMA connectors, but we can also offer FME, CRC9, TNC, MMCX, MCX and many more. If we have not listed your desired connector, please contact us for assistance.

If you require more information, we are happy to help. You can visit the product page for the specification sheet or you can contact us for pricing.
