Last week, an online amateur radio retailer contacted me about writing some blog posts for his website. One of the topics he suggested was “Choosing an HF vertical.” Here’s what I wrote this morning:Choosing an HF vertical
GAP TITAN antenna category is a curation of 19 web resources on, Gap Titan DX at DL8RDS, GAP Titan DX Test report, W9GF GAP TITAN DX Antenna Installation. Resources listed under GAP Titan category belongs to HF Vertical Antenna main collection, and get reviewed and rated by amateur radio operators.
For many amateur radio operators, a vertical antenna may be the only option they have to put up an HF antenna. They may, perhaps, live on a small lot, or they may not have suitable trees or other antenna supports from which they can hang dipoles.
Fortunately, there are many good products on the market. Unfortunately, there is some confusion about the different types of verticals out there. This short article will attempt to give you some guidance on how to choose the right vertical for you.
Trap verticals
Trap verticals have been around for a very long time. My very first HF antenna back in 1971 was a hy-gain 14AVQ. These verticals use “traps” that are parallel resonant circuits to electrically isolate portions of the antenna when transmitting on various bands. The traps make the antenna act as if it were a resonant quarter-wave vertical. For example, when the 14AVQ is being used on the 10m band only the lower portion of the antenna is active. When operating 40m, the entire length of the antenna is active.
*The Titan is a center fed GAP vertical, that provides a host of benefits in a rugged, yet manageable form. The Titan offers broad, continuous frequency coverage in a no tune, easy to assemble format. Designed to work in a limited space or as the perfect compliment to an antenna farm.
*After a lot of research, I purchased a Gap Titan DX from the Amateur Electronic Supply store in Las Vegas. The antenna is advertised as covering all bands 40 through 10 (including WARC) with SWR of 2:1 or less, and 100 KHz. Of 80 meters at 2:1 or less. A small capacitor at the top of the antenna determines what portion of the 80 meter band is.
Trap verticals need radials to operate effectively, and the more the merrier. Take this into consideration, when deciding whether or not to purchase a trap vertical.
No-radial verticals
In recent years, several manufacturers have introduced vertical antennas that do not need radials. GAP Antennas is one manufacturer that offers these kinds of antennas.
The manufacturers claim that these antennas are more efficient than trap verticals, and many amateurs use them with good results. There are some drawbacks, however. They can be difficult to tune, and they do require mounting at some distance above ground. The reason for this is that they are, in effect, vertical dipoles and if the end of the antenna is too close to ground, capacitive coupling will detune the antenna.
Non-resonant vertical antennas
A third class of vertical antenna that is becoming popular is the non-resonant vertical antenna. An example of this type of antenna is the LDG S9v43 Vertical Antenna, although several other manufacturers also make this type of antenna.
One reason that this type of vertical antenna is becoming popular is that it can be used across a wide frequency range. The resonant frequency of this antenna is actually about 5.4 MHz. With an antenna tuner, however, you can use the antenna on all bands from 80m to 6m. Adobe photoshop mac download cs6.
This tuner can be located in your shack, but for the lowest loss, you will want to locate the tuner near the base of your antenna. Don’t try using it with the internal tuner in your rig. On some frequencies, the antenna impedance will be quite high, and most internal rig auto tuners do not have adequate range to provide a 50-ohm match.
These antennas require radials. There is no formula to calculating the length of the radials, but they should be at least 0.2 wavelength at the lowest frequency that you wish to operate.Gap Titan Dx Manual
We carry the entire line of LDG vertical antennas. The LDG S9v43 antenna is 43 ft. high and covers 80m – 6m, the LDG S9v31 antenna is 31 ft. high and covers 40m – 6m, and the LDG S9v18 antenna is 18 ft. high and covers 20m – 6m. All of these antennas use heavy-duty, telescoping fiberglass sections. The antenna is self-supporting, and because it’s very light weight, easy to install.

I know it’s not a comprehensive guide to how to choose an antenna, but that’s not the intent. I also know that it’s a bit slanted towards the non-resonant vertical, but that’s the kind of antenna that the company carries. Having said that, I’d love to hear your comments.Gap Titan Dx ManualRelated posts:Gap Titan Dx Installation Manual During my research on the MFJ-1798 and other vertical multi-band antennas. I found the GAP Titan. For the most part, it was recommended by most owners. I happened to see a used one for sale at a reasonable price so I figured I’d see what the excitement was all about. After a lengthily battle with the seller who intended to shaft me by not sending the antenna, I finally ’convinced’ him to send it. I cleaned it up and installed it only to find it didn’t work. After several calls to GAP (great support) and two replacement orders later, I finally got it working. Seems it was either over powered or maybe even hit by lightening. Now I know why the seller didn’t want to send it. What a guy. These pictures detail the story. These pictures were taken near the end of September 2004. The first thing I found was the capacitor located at the top of the antenna has been damaged. The Titan is good for 100khz of bandwidth on 80m and this cap set the portion of the band that the antenna is resonant on. Customer specifies when ordering the Titan.

The following pictures are for help with assembly. The Titan manual is a bit lacking when it comes to detailed information on exactly where to place some of the parts. I talked with tech support and asked for the preferred locations. After assembly, I took these photos to document the locations and had tech support view and verify that everything was correct. My hope is that this might help those that are having the same questions I had.

Fortunately, this has been my only bad experience buying used equipment from a Ham. I am impressed with the quality and beefy hardware as compared to the MFJ-1798. I didn’t get to compare the two against each other but I did favor the Titan for these and other reasons. It does work fairly well and makes a great back-up antenna too so I’m keeping it. Plus in my opinion, it looks really cool!
