An HF low-profile antenna is used to verify the proposed method. The height of this antenna can be reduced to using the ferrite tiles, and the lower bound of the bandwidth can be reduced. Abstract: The design of low-profile, wide-band (WB), high-frequency (HF), vehicular, on-the-move (OTM) antennas is associated with a number of challenges, including their small electrical size, mounting constraints, and the diverse environment in the near field, to name a by: 6.

The antenna consists of 40 to 50 turns of copper wire wounded around a 60cm (24″) square frame. The dimensions and the wire wounds do not have strict tolerances. The following items are necesary to build the antenna: One frame 70xcm (½ x ¼″) Ikea RIBBA or similar.

Designing a Vertical Antenna Graphs cut through the mathematical headaches of antenna design. Put them to work and build a vertical that will shake the air with energy. By Walter Schulz,' K30QF ere is a vertical designed and built from graphs contained in The ARRL Antenna Book and ARRL electronics data book.

In my case the antenna was. Above: The Mark 1, Mod 0 Carbon-based, all terrain, night vision capable, 4X4, autonomous, high-altitude HF Wire antenna installation system.

I have the highest HF antennas in the neighborhood. I have found that almost any piece or wire or metal will work as an effective antenna on HF if it is long enough and reasonably in the clear.

Stealth Antennas MULTI-BAND PARALLEL-FED DIPOLES WITH ZIG-ZAG (NON-INDUCTIVE) LOADING This antenna has nothing new about its design, but it does bring together quite a few useful ideas and characteristics.

These are: • Fully no-tune antenna system for five popular HF bands; • Suitable for SWLs, QRP, M3 licensees and PSK31 operating plusFile Size: KB. It is important to recognize that the effective tuner resistance is a means to facilitate antenna design.

However, it can be used to estimate the associated tuner loss, and thus it sets the design guidelines for the development of tuners for low-profile wideband HF OTM antennas [28]. LPCA (Low Power, Crummy Antenna, not Log-Periodic Cubical Array or anything that exotic) is merely a new name for an idea as old as radio itself.

In the beginning, virtually all hams operated LPCA. Just a handful of parts (auto parts, in the early years) could get an operator on the air. Hundreds succumbed. Antenna works very well on all amateur bands within its' frequency range (I use a Yaesu FTD with a built-in antenna tuner).

Antenna tunes up fine with less than SWR on my meter. Have made many contacts primarily along the east coast with good signal HF Vertical Antennas and Packages. A vertical HF antenna offers many advantages—an omnidirectional signal collector and easy to install radiator are two of the biggest.

HF verticals are versatile, and can deliver both multiband and monoband performance. When used in a multi-vertical array, verticals can even provide low-band directivity. Build This Novice Four-Band Vertical Basic Amateur Radio: Putting your first amateur station together can be an expensive proposition.

One way to cut costs is to keep the antenna simple. Here's how I shaved the price and provided four-band operation.
