Every radio amateur should have a NVIS (near vertical incidence skywave) antenna for local and regional contacts. You may already have a NVIS antenna in your yard.
In this video, Dave Casler (KE0OG) discusses how to design, build, and use this practical antenna. In the simplest terms, any dipole antenna mounted approximately 1.8 wavelength above ground should work very well. If your dipole is cut for the 40 meter band, all you have to do is support the antenna 17-feet (5.182-meters) above ground. That height should give you a range of approximately 300 miles/482.802 kilometers).

Here are some comments from Dave (KE0OG):
Michael, KF0GZC, wants to get a simple NVIS antenna. He asks Dave for any suggestions, either to buy or to build. Watch to see what Dave says!

This video explores building a simple Near Vertical Incidence Skywave (NVIS) antenna. The presenter discusses optimal antenna height and radiation patterns for various frequency bands. Learn about dipole and multiband antenna considerations for short-range communication.
Thanks to "Tinker John" (W5CYF) for this inexpensive, homebrewed cable window pass through project. All you need are a few basic tools, bulkhead connectors, and small lumber pieces.

Here are some comment from "Tinker John" (W5CYF): A simple and effective method of passing coax antenna cable through a window sill. Easy and inexpensive to make. Used for any type of antenna cable including ham radio, TV, CB or SWL. Suggested items that may be related to this video: https://www.amazon.com/shop/w5cyftink... This video shows how to create a window pass-through for coax cables, using readily available materials. The creator demonstrates a simple and inexpensive method for bringing coax cables from the outside into a ham shack, using a piece of printed circuit board and a pin...
If you want to experiment with unconventional antenna designs, please consider adapting US military HF antennas. These antennas are easy to build and perform well on several amateur radio bands. In this video, Walt (K4OGO) builds a Terminated End Fed V Antenna (TEFV). The antenna is broad banded, requires no antenna "tuner", and covers frequencies from 1.8 to 30 MHz.

Here's another great 6 meter band antenna idea from Hayden (VK7HH). This vertical antenna is based on the "classic Cobra Antenna" described by the late Bill Orr (W6SAI). The antenna is easy-to-make using a few basic tools, a PVC mast, some RG-58 coaxial cable, and a few connectors. This antenna is suitable for both home and portable use.

Here are some comments from Hayden (VK7HH): This is a really simple and easy to construct antenna that will get you on the air on the six meter band using only RG-58 coax! I needed a quick and simple antenna for my WSPR beacon over the summer season. Enter the coaxial dipole or aka flowerpot antenna!
