If you need a bit of gain (approximately 3dBi) for your next 10 meter band antenna, please consider this vertical antenna project from Ian (G0CNN).
In this video, Ian converts an old 5/8 wave CB antenna into a 5/8 wave 10 meter band antenna. The "reengineered" vertical is easy-to-make and performs very well with its new identity.
Ian takes us step-by-step through the entire process, which uses locally available materials and some simple tools found in your ham shack.

Here are some comments from Ian (G0CNN):
Further development of a design from the website below where a commercial 5/8ths wave CB antenna is reverse engineered. This enhanced model is tuned specifically for the 10m amateur band and also adopts a ferrite choke, which is an improved option over the air-wound choke which is also shown in the build.
The parts for this simple DIY build probably already exist in your shack? If not, they come to about £5 for the air-wound choke model, or about £10 if you go for the ferrite choke model. A list of parts:
Main Antenna = 3.5m RG58 coax + 3.25m of insulated wire
Air-Wound Choke = 3.6m RG58 coax (or) 9 Turn Ferrite Choke = 73cm RG58 coax (+ the ferrite) - a 12 Turn on a 52 or 61 core will use a little more coax, say 1m in total.
Matching Stub = 71cm Westflex 103 coax

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!
