Introduction

It is not always practical to erect full-size antennas for the HF bands. Those who live in apartments, condominiums and communities that have codes, conditions and restrictions, may be restricted to the use of miniscule radiators because of house rules, or simply because the required space for full-size antennas does not exist. Other amateurs may desire small antennas for aesthetic reasons, perhaps to prevent the neighbors in their residential areas from becoming annoyed at the sight of a high tower and beam antenna of full dimensions. There are many reasons why some amateurs prefer to use physically shortened antennas, and this page offers information on various schemes that can be employed to realize that goal.

HF Antennas for Restricted Space is an overview of the problem and some solutions. Also of interest are other articles on the subject.
