Good Morning TVARC Members in My Previous Posting on  Stealth Antenna in the Villages The Presenter Provided a Interesting Solution To Our Problems.
Unfortunately his "Solution" Is a bit Pricey in the area Of the Commercial "Matching Unit".

Materials for this build.
 FT140-43 ferrite toroid, https://amzn.to/3dqaeqw

22awg poly stealth antenna wire, https://www.amateurradiosupplies.com/...
One 100pF 15kVDC ceramic capacitor, https://amzn.to/3BCmZY2

The 150pF 15KVC Ceramic Cap may work better in some ROOFS So Get It as well

Just Substitute "Portable" for ATTIC/ROOF Like the Previous Video Or Built 2 One for Home And One For When You Go "PORTABLE"
