To return or exchange an item, please reach out to our dedicated customer service team at sales@smileyantenna.com. Should you require a connector exchange, simply unscrew it from the bottom of the antenna; our team can assist with this process. Our antennas undergo meticulous fine-tuning using specialized tools such as the Bird Watt Meter to ensure optimal performance even without a ground plane. It is important to note that due to varying factors, the readings on your SWR meter may not always be entirely accurate. We recommend conducting a field test on your antenna and contacting us promptly if you suspect any issues. If necessary, you can return the antenna to us for further testing, and we will provide you with regular updates on the results. Please be assured that incidents of antenna failures are exceptionally rare in our quality products.
