The Mike range consititutes the all popular Mike 2A which is our highest gain (5 dBi) mag mount antenna covering global GSM/GPRS as well as 3G and ISM bands. Furthermore the Mike 2A is provided with the top of the range low loss cable to ensure end to end integrity.

Standing at just 97mm (height), the Mike 1B is the smallest member of the Mike family of antennas covering Quad band GPRS and 868 MHz (ISM). The Mike 1B is unique with its size and performance within the range of technologies it covers. However, measuring just 17mm (thickness), the Mike 3A is our most compact Mike antenna. Designed for location based services and solutions, the Mike 3A boasts a peak gain of 28 dB.

The Mike range of antennas are supplied with a variety of cable types, length and connectors to suit different industries. Custom cable types, lengths and connectors are provided for volume orders.

The Mike family of antennas are designed with convenience, performance aand robustness in mind. The easy to install Mike antennas provide a solid and versatile mounting method.

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.....
