Biconical antennas are notorious for having horrible VSWR properties especially at the lower frequency range. It’s the nature of physics, the lower in frequency, the large the antenna needs to be. To minimize impedance mismatch errors, it is recommended that high-quality in-line attenuators be used to reduce reflections. Here is a cool little VSWR calculator (https://www.ahsystems.com/EMC-formulas-equations/VSWR.php) with an option to add an attenuator value to see the overall improved VSWR.
In the realm of RF (Radio Frequency) and microwave engineering, maintaining signal integrity is crucial for optimal performance. This article (https://www.ahsystems.com/articles/fixed-attenuators-and-their-role-in-minimizing-impedance-mismatches.php) will explain what impedance mismatches are, what fixed attenuators are, how they function, and their importance in minimizing impedance mismatches
