This is post 2398 in a continuing series of simple ham radio antennas.
Thanks to Jarrad (VK3BL) for this simple antenna switch box project.
Here are some of Jarrad's comments"
We discuss why Mr. T (connector) is best left as a TV Star, and why they're not suitable for use as an antenna splitter in a Ham Shack. We cover the Mini-Circuits ZSC-2-2+ HF Splitter, and why its such a good solution to the problem of splitting an antenna between receivers, especially if you want to do accurate comparisons. We also cover how to use the 'RX Loop' on the IC-7610, and demonstrate using it to split the received signal between itself and the Icom IC-R8600. Stay QRV for lab grade transceiver shoot outs, with directly recorded audio from each so you can make up your mind for yourself :) Please feel free to be in contact a…

Thanks to Dave Tadlock (KG0ZZ) for this simple 2m/70cm vertical dipole antenna project.  This antenna is perfect for deed - restricted housing and field operations.
Also, Dave provides a link for more details on the antenna:

This is post 2396 in a continuing series of simple ham radio antennas.
In this well-paced, tightly organized video, Tim Carter (W3ATB) shows us how to build and install a basic 80 meter NVIS (near vertical incidence skywave) antenna.  Most of the materials for this project can be found locally or in your "junk box,"
NVIS antennas can provide reliable, strong signals out to about 300 miles/486 km.  These antennas are perfect for local, state, and regional communications.
Thanks for joining us today.

End Fed Half Wave Antennas are simple, compact, and highly portable.  The secret to an effective EFHW antenna is the 49:1 transformer which matches the impedance of your transceiver to the extremely high impedance of the antenna itself.
In this video, "Tech Minds" shows us how to build a basic 49:1 UnUn which will protect your transceiver as well as deliver maximum efficiency for the antenna.
Here are some general comments from "Tech Minds":
Here we take a look at an End Fed Half Wave antenna which is resonant on many HF bands due to a 49:1 matching unit being used. Antenna Design Plans: http://www.infotechcomms.net/download...

Every radio amateur should have a "go-kit" for portable or emergency operations.
In this video from Michael Martens (KB9VBR), we see how simple a portable field kit can be--Michael's kit has only three well-packed bags.
Here are some of Michael's comments:
What do I carry with me when I hit the road for a Parks on the Air of some other kind of portable radio activity.

This is post 2393 in a continuing series of simple ham radio antenans.
This video from Josh Nass ("Ham Radio Crash Course") discusses the various antennas that can be used in deed-restricted properties (HOA/CC&R).
This program was part of a live podcast from 08 August 2020. If you're living in an antenna-controlled apartment or home, you may find some of suggestions helpful in getting and staying on the air.
Here are some general comments from Josh:

Stealth Indoor HF Radio Antenna

Here's a great HF indoor antenna from Josh Bloom.  With a little planning and approval from your significant other, a fully disguised antenna will help you cope with deed-restrictions on outdoor antennas.
As Josh suggests, best performance will be reached using the various digital modes with low power.  Just remember the old saying, "A compromised antenna is better than no antenna."
Here are some general comments from Josh:
This is a very short video on my 10-75 meter wire antenna mounted inside my house due to my landlord. Works pretty well and very easy to do. I happen to be using JT8Call, but any digital mode would be fine. Voice could work, but make sure to keep the power reasonable. ----- Thanks for joining us today.
