Multiband HF Projects - Vertical Antennas

A $20 HF Mobile Antenna by KM4IE
A few hours of fun with PVC and wire and you’ve got yourself a respectable road radiator!

Much taller than the average Ham mobile antenna, this tree branch snapper tops out at 17 feet, 10 inches above the road. The antenna itself is 3.42 meters or 11 feet 2 inches long from the top of the mounting spring to the tip.

As a lot of you will appreciate, to work good DX requires a low angle of radiation from the antenna. It is possible to achieve this low angle with a horizontal antenna, but only if sufficient height above ground can be achieved.

Many amateurs are very restricted with the space they have available for HF antennas. I have documented a short antenna for the HF bands, but here is a simple method of mounting it, and a method of further reducing the length.

You may have already seen my HF Balcony Antenna which was designed solely for 14MHz, then a coil was added to cover all the lower HF bands (10, 7 and 3.5MHz).

Build This Novice Four-Band Vertical by WB1FSB
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.

Click to enlargeDe "SCREWDRIVER" Antenne door PHØRMH
Nevenstaande antenne, de “screwdriver” antenne wekte mijn belangstelling op de Hamvention 2000 in Dayton. Op verschillende, voor zendfanaten interessante stands, stond het ontwerp van Don Johnson W6AAQ.

Another nice antenna is very suitable for owners of an IC706 or FT817, but of course it is also usable with other transceivers and receivers. With this antenna you can be QRV everywhere within a few minutes, ...

Click to enlargeMobile/Portable HF Whip by G3YCC
I thought it may be of interest to describe simple to make HF whip antennas I have experimented with and used for a while.

The purpose of this project is to design a simple multiband vertical dipole antenna for 20 meters and above, with a tuner, that will provide gain and a circular pattern on the higher bands.

The Offset Multiband Trapless Antenna (OMTA) by AL7KK
Once in a while an idea turns out to be so good that it can’t stay a secret. The offset multiband trapless antenna (OMTA) is so simple to build, so easy to employ and works so well, it fits that category.

Click to enlargeShort Antenna by SMØVPO
"QRP" operation often means operating in remote places where a decent full-sized antenna is not possible. I personally live in an appartment where I am unable to erect large antennas.

St. Louis Vertical by NFØR
The St. Louis Vertical (SLV) offers portable enthusiasts an easy-to-build, easy-to-use antenna which covers 10-40M via a balanced line tuner.

Click to enlarge"Vipormutant" Antenna by ON6MU
Versatile Inexpensive PORtable MUlti-band Tunable ANTenna. Well yes, one must have a name HI...It is nothing more then a base coil loaded antenna, but with a selector direct on the base to tune the antenna.
