19dBi Directional Panel Antenna with Reduced Sidelobe Level

Top quality 19 dBi panel antenna for a 2.45 GHz band

DC short - as all Elboxrf's antennas - for static electricty protection and a low-frequency grounding

Good impedance matching for 2.4 to 2.5 GHz

Is equipped with a high quality mast mounting hardware allowing accurate elevation adjust

Can be mounted for a horizontal or vertical polarization. The picture shows an antenna in horizontal polarization - the H vector plane is parallel to a ground plane

Very rugged and completely weatherproof for long life in the harshest environments. The all stainless steel fasteners and aluminum bracket resist corrosion

Reduced Sidelobe Level Technology

In this oustanding antenna we have redesigned the array of radiating elements in such way that antenna is highly immune for signals come from distant stations, outside of the mainbeam direction. This is because all noises and interfering signals are not collected by highly suppresed sidelobes of this unique antenna.

TetraAnt_2_19_20_RSLL delivers a very strong and clean (high S/N) microwave power even in the most interfering environement. Is is especially sufficent in the dense urban area with a lot of microwave networks. Because the pattern of antenna is the same for transmit and receive mode it also do not interfers with other networks.

RSLL technologie:
Because an antenna works in the real environment, it usually sees many manmade and natural sources of background noise like a thermal noise from the ground, cosmic noise, sun, lightnings, discharges and so on.
So that the microwave power delivered to the radio will be the desired signal and noises collected from various sources.

Noise may be received through the main beam of the antenna pattern and through sidelobes. We have a very little chance to suppress noises received through the main beam, but we can to control the level of highly undesired sidelobes.

The new series of RSLL antennas have the sidelobes level reduced by no less than a 20dB compared to the main beam.
It means that the RSLL antenna will receive much less noise and undesired microwave power from other WLAN subscribers than a standard antenna.
