4.2. چڙهڻ
- چڙهڻ جو هنڌ چونڊيو: Select a high, clear location free from obstructions (trees, buildings, power lines) to maximize signal range. A sturdy mast or pole is recommended.
- محفوظ ماؤنٽنگ بریکٹس: 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.
- گرائونڊنگ: 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.
- ٽيسٽ ڪريو: 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.
- ترتيب ڏيو جيڪڏهن ضروري هجي: 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.
