A 1/2 wavelength dipole is one of the simplest antennas you can build and install. Some wire (it can even be scrap/salvage) a few insulators, rope, and a feedline. These can be built much cheaper than purchased, a nice thing once you’ve spent several hundred bucks on the transceiver.
468/F is the formula for get the 1/2 wavelength of a given frequency. Cutting this in half then gets you the 2 leg lengths that you feed in the middle for your Dipole Antenna.
