If you need an inexpensive rotating dipole antenna for Field Day or any other portable operation, please consider this antenna built by Chuck (KK6USY).
This antenna is based on a design from the late L.B. Cebik (W4RML).

Here are some comments from Chuck (KK6USY):
n this video I show how to make a Inverted U rotatable dipole antenna that is multibanded. This is an antenna design from W4RNL L.B Cebik (SK). Cebik designed this antenna for use on Field Day and other portable operations. I will make a version that uses 1/2" EMT conduit to keep the cost down. Two 10' lengths of the conduit cost me 14.50 at a box store, so not bad for a good performing antenna! Now this antenna can be made more light weight and portable using 3 sizes of Aluminum tubing and over all length can be abdout 3'. Check the ARRL antenna handbook page 21.17-18.
The conduit length for each side is 98.25", each side of the 15m is 55"

Don't let deed-restricted properties (HOA/CC&R) stop you from enjoying Amateur Radio. In this video from AC2RJ, we see how some well-placed trees, a camera tripod, a telescoping fiberglass mast, and a "V" antenna can get you on the air without a lot of effort. Add an antenna "tuner", a sturdy rig, such as the Yaesu FT-817, a microphone/cw key, and a simple grounding system, and you have a fully functional, nearly invisible ham station in your backyard.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=aeNHIQ_j4Dk This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH). Bernie does an excellent job of explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV). Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use. The G5RV is an excellent choice for the 20 meter band. Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.

Here's a way to use Amatuer/Ham Radio while you work on shedding a few pounds in useful exercise. Why not equip your bicycle for 2 meter/70 cm mobile operation? In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station. The project is straight forward, simple, and gives you emergency communications while you peddle down the road.
