Ham Radio Antennas for HOAs and Apartments
Suggestions
1. Flagpole Antenna
This one is probably one of the most common techniques used by Hams. A flagpole offers the perfect opportunity to employ a Ham antenna, and if you follow our advice, you will be the only one in your neighborhood that knows this. Vertical antennas are capable of serving both the HF and VHF bands, and as a smile worthy benefit, it gets very high stealth marks. Not even the local neighborhood HOA mall cop will catch this.
This is one of the antenna ideas for which there is a wealth of information, and if you go this route, it wont take much research to get your project going.
For the ultimate in stealth, use landscaping to conceal the wiring at the bottom of the pole, along with underground placement of the co-ax to your shack. The second picture here shows how plants can help. In addition to giving you the opportunity to efficiently get on the air, you can also fly the flag (but make sure to illuminate it correctly at night.)

2. Rain Gutter Antennas
Most homes have rain gutters, and most are made of conductive metal, either steel or aluminum. This technique shares the same high stealth marks as the flagpole, and when done properly, the concealment will be undetectable (at least to the HOA cops, both official and unofficial), and can be very effective. While this idea is not nearly as common as the flagpole, there are more than sufficient technical articles that will allow you to used your gutters for more than rain. See this one from the SCG Company:
https://www.sgcworld.com/raingutterinstall.html.
One note of caution, however. Time, the elements and gutter garbage will take their toll on your antenna quicker than with most other antenna types. Any homeowner who cleans his rain gutters can testify as to the magnetic like attraction that gutters have for leaves, dirt, and general gunk. Whether made from steel or aluminum, corrosion and rust will eventually present problems for your gutter antenna. Keep 'em clean and make sure that your antenna is operating at it's peak.
Few home owners will splurge for copper rain gutters, but for those who do, it is an excellent choice for this type of antenna. Many copper gutters are welded, greatly reducing (or eliminating) any breaks in continuity. Copper does not rust and will outlast any other material. Looks way better too!!!

3. Roof Top Wire Antennas
A roof top wire antenna can be one of the most concealable types for HOAs, and perhaps of the most efficient ways to get on the air. For those who have flat roofs with raised walls, the antennas, when mounted slightly below the walls, will not be visible to the roving bands of HOA mall cops. Or, if you are able to hide the properly colored wire in and amongst the shingles on a V shaped roof, and place it on the back portion of the roof, it will be likewise be almost invisible. if you are quiet about your station, no one should ever know.
With the right wire and a tuner, you can have access to many of the HF bands. This technique is really a win-win for the HF crowd. Check out DX Engineering for a selection of wire antennas,

4. Attic Antennas
In the attic, there is NO risk of detection from the outside. Other advantages of attic mounted antennas:
- The antenna will be shielded from the elements
- The antenna will be shielded from lightening strikes, as long as it is not connected to other antennas
There are a couple of things of which to be aware:
- Make sure that your roof doesn't have one of those metallic barrier shields
- Be careful of RF radiation, especially with high power transmissions

5. Low Profile Antennas
This category is attractive as the antennas are short enough to be hidden by most fences. A little help from nearby landscaping will add to your stealth.
Here are two mounts The first on a 3rd story apartment and the second in a back yard with some good landscaping camouflage, both are Scorpion antennas.

TW2010 - Capable of handling 5 bands, very efficient, and small enough to use in a back yard or on a camping trip.

6. Repurposed Satellite Dish Antennas
Unlike Ham Radio antennas, satellite TV dish antennas cannot be prohibited. As a starting point, this is a good one, depending on how you adapt it to your Ham Radio uses. The following picture shows a Satellite dish that was modified to include a couple of verticals, for VHF use. Although one could argue that the ever present HOA rule enforcement cops might not pay any attention to the extra things on the
satellite dish, there is a risk of detection, and perhaps a good one. Shorter and smaller diameter antennas (wire), in a color more likely to disguise it, could help. Also, mounting it on the rear portion of the house, where it is not as visible to the street walking or vehicle riding cops, could also help.

There is another method for repurposing a satellite dish for Ham use, and it is nearly 100% undetectable. It is referred to as a "horizontal slot" dish and employs the use of an actual slot cut into the dish. The explanation is long, but the attached PDF gives sufficient detail to get you going, if so inclined. It is described as the master of disguise and high in performance. It looks something like this (look for the upside down U):

7. Inside The Yard Wire Antennas
This one is fairly straight forward, simple, and easy to accomplish. It does present the risk of nosy neighbors looking over your fence. With regard to these risks, one cure would be the benefits of concealment landscaping, as will a good relationship with your neighbors. At least from the perspective of roving neighborhood rule enforcement types, this back yard solution offers a high level of concealment.
Of all the various stealthy techniques discussed in my posts, I was shocked to fine an almost complete absence of pictures of these types of wire antennas. Whsile the pictures below are not the best, they offer a decent view of this type of antenna.

8. Roof Vent Antennas
Vent antennas are commonly used for VHF and UHF frequencies. The Ventenna Company makes the one that you may have seen in many Ham magazines. All roofs shave vent tubes extending through the roof, and often,they have an ugly tall appearance, even without the capability of an antenna. This is the reason why having a high vent is entirely consistent with the way homes are built. Ventenna capitalizes on this and offers a stealthy means to get on the air, see:

NOTE: The Ventenna gets a 4.7 rating on E-Ham (

9. Hidden in Trees Antennas
For those who can, using a tree to conceal an antennas is a great way to use a high efficiency antenna, located up high. Nuff said.

10. Truly Unique and innovative Antennas
A. Never thought of a dual purpose canoe. Here is a 20M canoe antenna from
http://www.n6cc.com/tactical-antenna-systems. Absolutely ingenious!!!
They said:
See that 17 foot aluminum Grumman canoe (hint – mounted on those black plastic rack-mounts)? I see a quarter wave horizontal mobile antenna for the 20 meter Ham band. It worked fine! (with a little help from impedance matching)

CONCLUSION
One of the more appealing things about Ham radio, and perhaps one of it's founding principles, is the welcome environment and the opportunity to experiment and build your own stuff. Getting on the air when your friendly HOA has worked hard to ban those nasty Ham radio antennas, should be a challenge, and not a reason to surrender. You don't need to be an engineer, a rocket scientist, or an antenna designer to come up with clever solutions to your antenna situation. All you will need is the motivation, an imagination, and maybe a little help from others who have faced the very same problems as you.
Eleven years ago we did a net that featured a member who built a 2m antenna from a broken lawn chair. It worked, and I'm quite sure that no one could have found instructions in any book or reference on just how to do that. He did it and it worked. Check it out here:
viewtopic.php?f=70&t=1243.
The ARRL has several antenna books available for sale, and this would be a good place to start, if you have the motivation. Good luck!!!
