A helpful guide on how to determine the right length of coaxial cable for your antenna.  The video from YG1CCR also shows you how to make coaxial cable work as an impedance transformer and how to make proper SWR measurements.

160m Short Vertical Loft Antenna-G3XBM QRP WEBSITE https://sites.google.com/site/g3xbmqrp3/antennas/160m_loft_ant. Author:  Roger (G3XBM). Please click link to read the full article. Thanks for joining us today. Aloha es 73 de Russ (KH6JRM) Comment: In a previous post, I showed how a little creativity and experimentation can launch a full-sized 160 meter Amateur Radio antenna.  Fortunately, the two radio amateurs in this video had enough land and tall supports to make this antenna work. If you don't have these advantages, can you still get on 160 meters with a usable signal?  If you're Roger (G3XMB), the answer is a resounding "Yes".  By adopting a modified helical antenna design, Roger was able to put a small 160 meter vertical antenna in his loft (attic).  The idea was to wind a length of PVC piping with as much wire as I could find (a bit like a helical, but on 160m), attach some top capacitance in the form of a couple of horizontal wires, bring

Now that the solar minimum is coming, more radio amateurs are finding the joys and challenges of working the lower HF bands,  such as 40,80, and 160 meters.  One of the major problems working the lower HF bands is getting an efficient, cost effective antenna for these frequencies.  Antennas for 160 meters can be quite large, requiring a good-sized piece of property to accommodate these "skyhooks."  In this video by "AllAmericanFiveRadio", we see Dave and a friend use a variety of approaches in building, launching, and using this large antenna.  Key to the success of this project was the use of a pneumatic weight launcher to place antenna wires near the top of several trees.  The device is quite clever and effective.  In the past, I've used a slingshot and a bow and arrow to launch lower HF band antennas.  This launcher cert

Easy SWR Adjustment Calculator for Vertical and Dipole Antennas. Post #1440. https://www.momcx.co.uk/quick-swr-calculator-for-vertical-and-dipole-ham-radio-antennas/. Author:  M0MCX.

Comment: Here's a handy adjustment calculator and spreadsheet for choosing how much to trim your antenna elements to resonance.  This helpful antenna trimming tool will come in handy if you need to add or cut wire from your dipole or vertical antenna elements during portable, emergency, or Field Day operations.  Just download the program and you're ready to go.

Operating an Amateur/Ham Radio station from a deed-restricted property (HOA.CC&R) is often a daunting challenge.  If outdoor HF antennas aren't permitted in your area, perhaps a dipole antenna mounted in your attic will get you on the air without raising the ire of the "antenna police."  If your ham radio station is in a wood frame home with non-metal shingles, this idea from K5ACL (SignalSearch) will solve most of your antenna problems.  The video takes you step-by-step through the design, construction, and use of an attic HF antenna.  Another approach would be to use some kind of magnetic loop antenna, either home-built or commercially made.
