This section provides instructions for assembling and installing your FMUSER CB100 CB Base Antenna. It is recommended to have assistance for safe installation, especially when working at heights.
4.1. פֿאַרזאַמלונג
- ידענטיפיצירן קאַמפּאָונאַנץ: Lay out all antenna components and familiarize yourself with each part as shown in Figure 3.1.
- Attach Radiating Elements: Carefully connect the aluminum radiating elements to the antenna base unit. Ensure all connections are secure but do not overtighten. Refer to the diagram for correct order and orientation of elements.
- Install Ground Plane Radials: Attach the ground plane radials to the designated points on the antenna base. These typically extend outwards from the base.
- קאָננעקט קאָאַקסיאַל קאַבלע: The antenna features an SO239 UHF Female connector. Connect your 50 Ohm coaxial cable (PL259 UHF Male connector) to this port. Ensure a tight, weatherproof connection.
- Verify Total Length: Once assembled, the antenna should measure approximately 18 feet in total length.

4.2. מאַונטינג
- קלייַבן מאַונטינג אָרט: Select a high, clear location free from obstructions (trees, buildings, power lines) to maximize signal range. A sturdy mast or pole is recommended.
- זיכערע מאַונטינג קלאַמערן: Attach the provided U-bolts and mounting brackets to your chosen mast or pole. Ensure the brackets are securely fastened and level.
- Mount Antenna: Carefully lift the assembled antenna and secure its base to the mounting brackets using the provided hardware. Tighten all bolts firmly to prevent movement in wind.
- Route Coaxial Cable: Route the coaxial cable from the antenna to your CB radio, ensuring it is secured to the mast and building to prevent damage from wind or strain. Avoid sharp bends in the cable.
- גראָונדינג: Connect the antenna system to a proper earth ground using a heavy-gauge wire and a suitable grounding rod. This is crucial for lightning protection and optimal performance.

4.3. VSWR Testing
After installation, it is essential to test the Voltage Standing Wave Ratio (VSWR) to ensure optimal performance and prevent damage to your CB radio. An SWR meter is required for this step.
- Connect SWR Meter: Connect the SWR meter between your CB radio and the antenna coaxial cable.
- דורכפירן טעסט: Follow the instructions for your SWR meter to measure the VSWR across the 27MHz CB band. Aim for a VSWR reading as close to 1:1 as possible, ideally below 1.5:1.
- סטרויערן אויב נייטיק: If the VSWR is too high, minor adjustments to the length of the radiating elements or ground plane radials may be required. Consult a qualified technician if you are unsure.
