Antennas of three types are applied in the georadar High frequency shielded antennas 100, 300, 500, 900 MHz, 1.5 and unshielded 2 antenna are
similar and differ only in dimensions. Theese antennas are intended for operating mostly in contact with the groung. The low frequency antenna 38-75-150 MHz is of the dipole type with replaced dipoles for operation at frequencies 150, 75 and 38 MHz. That antenna may be used in isolation from the ground at distance 0.15 - 0.4 m as well as in contact. Shielded air- coupled 750 MHz antenna operates only in isolation from the ground at distance 0.2-0.3 m. 2. PREPARING OF THE GEORADAR TO OPERATION. 2.1. Connection of units. Before to begin to make any connections and switching on please read thoroughly the instructions below and strictly follow them when connecting units of the georadar. The connection diagram of units is shown in Fig. 1, 1 a and 1 b. Warning! Before connection of any cable to the Control Unit make sure that it is turned OFF. It is strongly prohibited to connect or disconnect any cables to the Control Unit or antenna while the Control Unit is powered. 1) Place an IBM-compatible Notebook computer to the special platform located on top of the control unit (Fig. 2a). The platform can be turned and fixed in two extreme positions. Before installation of the computer remove fixing brackets made of stainless sheet steel. Applying screwdriver unscrew for 1 turn screws fixing movable strips 2. They are free now and may be stand at distance equal to computer length If it is necessary to adjust the platform to the computer width unscrew in full screws fixing movable strips 2 and take away movable strips. Unscrew for 1-1,5 turns screws fixing the movable bracket 3. Now brackets 3 can be moved along slots 4 and adjustment of fixture according to dimensions of the computer is possible. It is recommended to make this placing the computer on the platform. Adjusting up positions of movable strips 2 and brackets 3 mark they positions by pencil. Take away the computer and screw screws fixing movable brackets 3 and strips 2. Do not apply efforts tightening screws since this can cause deformation of the strip. Place the computer and fix by means of fixing brackets made of stainless sheet steel. Should fixing stand 6 with the fixing bracket hinder to operate the computer, it can be moved into another position 7. 2) Connect the data communication cable to the control unit and to the LAN connector of the computer as shown in Fig. 1. 3) Connect the power cable to the control unit and to the battery. 4) Assemble the antenna. If a high frequency antenna is applied (1 00, 300, 500, 900 MHz, 1.5 or 2 GHz), it is required to attach the handle and to connect the antenna cable to the antenna. 3-m antenna cable should be attached to the handle by plastic clamps or adhesive band as it is shown in Fig.3. 20-m antenna cable is fixed on antenna by special clamp as it is shown in Fig.3a. The 100 MHz antenna is combined as shown in Fig. 6. Each 100 MHz antenna has two 5-pin connectors. Attaching cables to antenna operator may use any of two connectors because they are connected in parallel. If odometer wheel is needed it is attached to antenna as shown in Fig. 3b and 6a. Survey wheel is connected to antenna via 3-pin connector. The operation combination of the low frequency antenna 38-150 MHz is shown in Fig. 5. Transmitting and receiving antennas are fixed to the grip via articulators those may be fixed at
angles of 0, 30, 60 and 90 degrees to the vertical. The cables are attached to the grip by plastic clamps or adhesive band. After joining of cables in the middle of the grip they should be fasten together by adhesive band every 10-15 cm. The method of attachment of 0,5 m (150 MHz) and 1 m (75 MHz) dipoles is illustrated by Fig. 7. To operate at frequency 38 MHz attach additional dipoles according to Fig.8. The operation combination of the 750 MHz antenna is shown in Fig. 12. Special cable with color rings on connectors to be connected to antennas is provided. Assambling antenna you have to coincide color marks on antenna connectors and cable. 5) Connect the antenna to the control unit. Usually one antenna unit is used for profiling because it contents both transmitting and receiving antennas. In case when separated antennas for transmitting and receiving are needed (for example in measurements by Common Depth Point method) the second antenna is connected to the Control Unit as it is shown in Fig1 .b. In this case antenna 1 transmits but antenna 2 receives signals. 2.2. Switching ON of the Georadar.
