Key Features:
  • Designed for 4G/LTE 2600MHz
  • Will also work at 3G/UMTS
  • Wall/Pole mounted
  • Antennas with adhesive fixing
  • Direct connect and Through-hole

 

The ALPHA 40 family is a familiar 'T' bar style antenna that has been designed specifically for 4G and 3G frequencies and is in the adhesive mounting range.  The ALPHA 40 has been tuned to give maximum gain at 4G (2600MHz) frequency but only slightly lower gain at 3G (2100MHz) and 2G (1700-1900MHz) frequencies. The ALPHA 40 can also be used for Bluetooth and WiFi applications with great success.

 

The Delta 40 direct connect 4G antenna is tuned primarily to give good performance at 2600MHz in a small package. However, a reasonable performance can be had at 3G frequencies as well. If you only need 4G/3G frequencies in a direct connect antenna then the Delta 40 is a great solution without going to the larger Delta 41.

 

The Oscar 40 family is a great antenna solution coverring many popular frequencies in use today. Its radome is UV proof and water proof making it a great outdoors antenna. Fitted with low loss cable as standard really makes this antenna the standard item to fit in most outdoor applications for 4G/3G/2G and WiFi.

 

The Tango 41 is a wide band outdoor antenna aimed at the 4G / wifi frequency but equally capable of 3G and 2G frequencies. With a small footprint of 39.8mm diameter the Tango 41 can be positioned into small places or on cabinets with curved or non flat surfaces easily. The Tango 41 has an integrated RF cable terminating in any connector you need but as standard SMA male.

Extend your reach with Siretta quality, low-loss RF cables

Acquiring RF signals in poor reception areas (2G/3G/4G), short range wireless communication (line of sight for 433 and 868 MHz) or WifI connection in large buildings will require high gain antennas placed as high as possible to get the best reception. Problem is that the longer the cable length is from the RF equipment to the antenna, the higher the losses and consequently poorer reception. RG174 and RG58 are standard cables that everyone use for RF work, however the losses per metre escalate rapidly the higher the frequency goes. Antennas with cable lengths of 10M, 15M or 20M will suffer considerable loss over the length. It means that a more powerful transmitter and /or a more sensitive receiver is required. This all comes at a price in one way or another. Better to not have the losses there in the first place. Standard RG58 cable has an approximate loss per metre of 1dB at 2.5GHz - Wifi and Euro 4G frequencies. Bear in mind that a loss of 3dB of signal is actually halving the signal strength it is easy to see why systems are not very sensitive if they have long and standard cables to the antenna. Now take the LLC200 low loss RG58 equivalent it has a solid copper core and 2 levels of shielding and special connectors to accommodate the cable. It has a 0.55dB loss per metre at the same 2.5GHz frequency. Bearing in mind the logarithmic nature of measuring in decibels the signal arriving at the end 20M of RG58 cable at 2.5GHz is about 0.07% of what went it to the cable. Alternatively, using the LLC200 cable the signal arriving at the end of the cable is around 12% of what went in. 0.07% versus 12% is a massive difference in signal strength. This is the case for Siretta\'s low loss cable range! Siretta’s low loss extension cables provide the best solution in minimising losses and giving the required RF signal for a successful and continuous wireless connection. Generally speaking low loss cables are not very available as a stock item, however at Siretta we have a complete range of cable lengths and connector styles from stock or very short lead time. Available in cable lengths from 5m to 20m with a vast number of connector combinations, including, SMA, FME, N-Type and TNC etc. Look for the white cable marker telling that it is a Siretta quality cable, its part no. and length.....
