Comment: I found this fascinating article today while I was searching for some experimental antenna designs.  Having once lived in a "no antenna" HOA/CC&R neighborhood, I remember how frustrating it was to design and build an indoor antenna to get me on the air. After a few botched experiments, I finally was able to build a simple indoor loop fed by 450 ohm ladder line to get on HF and a simple VHF ground plane antenna for my 2 meter work. This collection of indoor antenna projects should give you some ideas of what can be done to get on the air from deed-restricted housing. Try some of these indoor antennas and see if you can find a way to get on the air. Being off the air i

Comment: According to Moscow radio amateur Peter Dabizha (R2ABY), many hams in the Russian Federation  are enjoying operating "in the field" with portable QRP rigs and homemade antennas , such as the magnetic loop featured in this article. Some of the antennas used by Russian QRP enthusiasts are very short, with many vertical antennas measuring only 3 meters/9.84 feet long.  Add to this mix, the cold Russian winters and you have a real survival operation for not only the well bundled operators but also for their assortment of portable rigs.  Such events are becoming popular in the United States as well, usually held under the title of "Winter Field Days." It pays

The K2MIJ 30 meter "Limbo Stick" antenna. Post #1038.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=L3coh5JXZOA. Here's a 30 meter vertical antenna that is only 9 inches/22.86 cm tall, including the "halo" which serves as a "top hat."  According "visualjuiceman", the antenna works quite well on the 30 meter Amateur Radio band and exhibits a low SWR (see photo of the MFJ HF/VHF SWR Analyzer, model MFJ-259B).  The coil consists of a 2 inch/5.08 cm PVC form using 26-24 AWG wire. The radiator is made from #10 AWG wire.  This antenna is very "stealthy" and could be used in deed-restricted properties. Why not make one of these super small antennas and have some fun?

If you're having trouble viewing this video, please enter this title URL into your browser search box: https://www.youtube.com/watch?v=v0Tb_hXYUIQ. Here's a simple, basic halo antenna that will get you on the often exciting and somewhat challenging 6 meter amateur radio band .  This band is often called the " Magic Band " because of its HF and VHF characteristics. This short video from KD7DHB shows one way of building an inexpensive, yet effective antenna for this band. Most of the materials can be found at the nearest building supply or home improvement center.  You may have to buy the coaxial cable from a ham radio store.  A few hours effort will reward you with a basic antenna that performs well and is easy to raise and lower.

Getting 160 meters on a budget. Post #1036.

Getting on 160 meters on a budget (http://www.eham.net/articles/21292). Accessed on 07 February 2017, 20:05 hrs, UTC . Author:  NO6L. Please click link or enter title URL into your browser search box to read the full article. Comment: As solar activity wanes and propagation gets more difficult on the higher HF bands (20 through 10 meters), radio amateurs are finding plenty of dx and local contacts on 160, 80, and 40 meters.  Forty meters is becoming a "workhorse" band for regional nets, local rag chews, and fairly good DX after the sun sets. Eighty and 160 meters also offers some excellent propagation at sunset and sunrise, as well as reliable communications during the day.  The one major drawback to antennas on 80 and 160 meters is the sheer size of dipole or vertical antenna for these bands.  According to NO6L, all is not lost if you want to explore the benefits of the 160 meter or "gentlemen's band."  If you can find enough space for even a com
