Top loaded HF vertical antenna with ground tuning unit

Thanks to Australian radio amateur Peter Parker (VK3YE) for this easy to understand tutorial on how to build a top loaded HF vertical antenna with a ground tuning unit.  This antenna is ideal for small urban lots or for portable operations.  Besides the basic antenna, all you really need is a decent ground radial/counterpoise system to complement this reduced size vertical antenna.

Here are some of Peter's guidelines:

"Don't have much height but have something metal underneath? If so a top loaded vertical is a great antenna to try. Just 10 metres wide and 5 metres tall it will even load up on 3.5 MHz. Especially if you're over salt water, you're unlikely to get anything better for its size. The key items needed include wire, two poles, a simple antenna coupler (an L-match is fine), something to clip onto the counterpoise railing and a ground tuning unit. I'll probably describe a more refined version later but it comprises a variable capacitor in series with an inductor. It's also desirable to have an RF current indicator. PS: Like these videos?
