Reduced Sidelobe Level Antenna
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 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.

The RSLL antennas:
- TetraAnt_2_19_20_RSLL - especially designed for a "clean up" highly unefficient 2.45GHZ WLAN networks. Now there is no need to switch the entire 2.45GHz network to the 5GHz band. You will see benefits by using this precise RSLL antenna!
- TetraAnt_3_19_20_RSLL - the high performance WiMAX 3.5 GHz antenna for point to point microwave links. Redesigned the array of radiating elements make antenna highly immune for signals come from distant stations, outside of the mainbeam direction.
- TetraAnt_5_23_10_RSLL - the high quality 5 GHz antenna for point to point microwave links. Also excellent as a subscriber antenna.
- TetraAnt_5_19_20_RSLL - the top performance subscriber 5 GHz antenna for point to point microwave links. The successor of the well known TetraAnt_5_19_16
Zero Squint Error
The squint error means that the elevation of the mainbeam changes when the operation frequency varies. This is especially apparent in serial-fed sector or omnidirectional antennas.
The user sees a sharp drop in the signal level after the channel change. The result is decreasing of the data throughput or even loss of a microwave link.
The Elboxrf's antennas have this problem eliminated ensures undisturbed life operation.

The RSLL and Zero Squint Error sector antennas:
- TetraAnt_3_14_90_V_RSLL - The RSLL and Zero Squint Error makes this antennas excellent choice for a high performance WiMAX 3.5GHz network.
- TetraAnt_5_14_90_V_RSLL - Very wideband 14 dBi sector antenna for a high performance 5-6GHz network. Enables to work even in very radio crowded environments.
- TetraAnt_5_16_90_V_RSLL - 16 dBi sector antenna with highly suppersion of unnecessary sidelobes over and under horizon. Flat gain accross the band enables outstanding operation for the 5 to 6 GHz.
- TetraAnt_5_17_90_V_RSLL - High gain 17 dBi ensures extremaly high data troughput due to the RSLL and Zero Squint Error technology.
