A capacitance hat is a legit way to electrically lengthen an antenna. I have had decent success with them when finetuning antennas for lower bands.

- hippich 2y agothanks for the "capacitance hat" search term. from googling it looks like this hat is electrically connected to the antenna? In my case if the "cap" touches the copper wire of the antenna - signal strength decreased. Only when I kept the cap close but not touching the antenna it performed well.
- RF_Savage 2y agoSure, but that does not stop it from capacitively coupling it. Even tape or insulation from a wire can, be used to electrically lengthen or fine tune an antenna. But thats less about capacitance and more about the electrical lenght being longer in the dielectric.
