# Introduction

5.8GHz Clover

- leaf antenna works in the frequency band of 5.8GHz ISM. It can be used in the 5.8GHz

wireless video module AVL58 (both TX and RX), and also other transmitter and receiver working in the

frequency band of 5.8GHz. The product has the following characteristics: low profile, light weight, high

reliability and wide communication range. The cloverleaf antenna design has proven to be one of the best

antenn a designs for aero

- modeling activities, especially the FPV flying

.

The product has the characteristic of wide wave band range and circular polarization to ensure the stable

transmitting and receiving when the aircraft is in any attitude and position. So it can provide reliable

wireless video signals during a flight.

The ant enna has an advantage of good direction and has a wider and well

- distributed range of signal than

a common antenna

, which are important characters during a flight . ( Fig.1)

The RX antenn a’s coaxia l cable can be slightly bent to meet the need in different directions with a limited

angle of not larger than 28 degree (Semi

- diameter of the bent arc should not be shorter than 40mm)

,

which increase s the flexibility of installation. (Fig.2)

Please try your best to keep the antenna straight.

The antenna use coaxial cables of high quality, which assure s a better performance of this product.

# Attention s

 Please always mount the antenna before power on the device to avoid circuit damage.

 Please place the TX and the RX antennas according to the guide and ensure the two antenna

visible to each other (no obstacles), otherwise, the communication dist ance will be shortened.

 The ben t angle of coaxial cable NEVER exceeds the angle limit , otherwise, the performance

reduction of the antenna will occur or ever damage of the antenna may happen

.

 D o not bend the coaxial cable of the TX as possible as you can to avoid antenna performance

reduction

.

 Please keep the transmitter and the receiver away from the ground as far as you can to avoid

influencing the communication distance.



# Assembly

STEP1. Please mount the antenna on the transmitter and the receiver respectively. ( Fig. 1)

STEP2. Mount the receiver on the aircraft as the following chart to get a better performance. ( Fig. 2)

 Please try your best to keep the coaxial cable of the RX and TX straight

.

 Please keep the transmitter and the receiver away from the ground as far as you can to avoid

influencing the communication distance.
