@Edent that ‘rubber duck’ vertical antenna will do better if it has a counterpoise or a ground plane to act against. A ‘rat tail’ counterpoise is just a bit of wire 1/4 wavelengths long, connected to the outer shield at the antenna base. They’re most common on handheld radios. Probably the cheapest and quickest thing to test.
