The collection includes both wire and tube models, with tubular elements including some stepped-diameter versions and some uniform-diameter versions. Models cover all of the HF bands: 80, 75, 60, 40, 30, 20, 17, 15, 12, and 10 meters. If you see a design for one band without a counterpart for another band, you may scale the element lengths, spacing, and diameters to create the desired beam. There are 85 true Yagis, although there are a few V-Yagi designs that combine parallel-element coupling and element-end coupling. As well, the collection includes 15 Moxon rectangles, which also use both parallel-element and element-end coupling. See the VHF-UHF antenna collection for Yagis covering these higher frequencies.

The models cover quad sizes from 1 element up to 6 elements for 3.6 MHz through 1296 MHz. The set of 10-meter models especially shows a wide variety of variations, especially for diamond-shaped and square models with loading at the high-voltage points. The models with "opt" included in the filename are the products of a set of equation-based models in .NWP-format that cannot be included here. However, the calculation instruments are available at numerous sources. AWG #12 copper wire sample optimized quads appear for all bands from 80 meters to 1296 MHz. Besides monoband quad beams, the collection also includes a good number of 2-, 3-, and 5-band models ranging in size-per-band from 2 elements to 6-elements.

The collection of LPDAs includes both log periodic dipole arrays and log-cell Yagis, which use LPDA structures for their drivers. The log-cell Yagi models (labeled LC) are mainly on the very wide 10-meter band. The LPDAs proper (labeled LP) cover a very wide frequency range beginning at 3.5 MHz and ending at about 2 GHz. There are 3+ octave models, but most examples cover a 1-octave (2:1-frequency) range. Models also vary widely in size, with a preference for relatively high-performance LPDAs. Many include performance-enhancing modifications. The collection also contains some special purpose or non-amateur range models, including 3 FM LPDAs, some single-band LPDAs, and some government and commercial communications band versions.

The collection of verticals includes both vertical element antennas and antennas with predominantly vertically polarized radiation. The models tend to focus on the 160-meter through 30-meter bands. For those bands, there are simple monopoles over radial systems, shortened monopoles with a variety of hat structures, and numerous wire structures whose dominant radiation is vertically polarized. This group includes rectangles, hentennas, delta loops, quad loops, half-squares, bobtail curtains, Sterba curtains, and Bruce arrays. There are also a few parasitic and phased monopole structures. Besides these basic vertically polarized HF antennas, there are a number of others, including J-poles, the L-antenna, the collinear vertical, and a trio of dipole arrays.

The collection of wire arrays covers perhaps the widest territory of any of these collections, since there are collinear, end-fire, and broadside arrays. Hence, you will find extended double Zepps, 8JKs, and lazy-Hs among the offerings. The collection also includes some wire Yagis for the low HF range. As well, you will discover loops oriented both vertically and horizontally. Indeed, you will find rectangles, double rectangles, hentennas, half-squares, and bobtail curtains for the vertical radiation aficionado. Among the larger arrays are collinear extended double Zepps, Sterba curtains, and Bruce arrays. In addition, there are a number of wire loops potentially usable on several bands. The collection even includes a few long wires, Vee-beams, a rhombic, and some challenging NVIS arrays. Virtually all of the antennas use either AWG #12 or AWG #14 copper wire as the main ingredient.

The collection of phased-array models covers the HF spectrum from 80 through 10 meters, with a few models at VHF and UHF frequencies. Phased arrays (for the purposes of this collection) include any antenna that provides a feed to more than one element. Many are vertical arrays--especially in the MF and lower HF range, and some models are for the AM broadcast range. Upper HF designs are mostly horizontal, although some of these antennas may be used vertically to good effect. Among the antenna types included are collinear, broadside, and endfire wire arrays, 2-element horizontal phased arrays (ZL Specials, HB9CVs, and variations), stacked beams, dipole arrays, and turnstiles. Some models use the TL facility of NEC-2 to provide one or more phasing lines, while others use separate feedpoints.

The collection has samples of many kinds of antennas, including Yagis, quads, corner reflectors, planar reflectors, simple and collinear verticals, and dual rhombics. However, Yagis dominate the collection, since there are so many sizes, designs, and variations on them. The collection only touches on quads, since the separate collection of quad designs includes both HF and VHF/UHF quad beams. Some designs, like the DL6WU Yagi, may only have a small sample on a particular band, because you may create other lengths simply by removing directors one-at-a-time from the forward end. As well, many designs for 50 through 432 MHz scale readily to the upper UHF region. There are also a few FM band antennas, including a triplet of LPDAs. However, most VHF/UHF LPDAs appear in the separate LPDA collection.
