This really was very inspiring! I have a lightweight homebrew portable antenna that I built years before the Buddistick existed. The dimensions are based somewhat on the short version of the Hustler mobile mast and resonators, but with a tapped coil and telescoping whip section for tuning. The lower section makes use of a piece of RG-8 inside a small PVC pipe, using the shield of the RG-8 for the radiator. I designed it to attach directly to the SO-239 on the back of my FT-817. Recently I've thought about ways to get the antenna higher and out in the clear, but was stumped for ideas. After watching this I built a tripod adapter out of 1/8 inch ABS sheet and JB Weld plastic adhesive. Tested it today and it works great. Tomorrow's project is an aluminum adapter plate for the actual Hustler whip. Here's a tripod tip: If you have a photo tripod with a removable ball head, unscrew the ball head to get access to the 3/8x16 (3/8 course thread) stud. It's longer and stronger than the 1/4x20 stud that is made for camera mounting. A 3/8x16 wingnut works great to attach an adapter plate to the stud.

Remember what makes a permanent vertical work well also improves a portable vertical. A 1/4 wave or shorter antenna has a current maximum at the bottom (below the coil, if base loaded). Relatively high RF current from the shield of the coax PLUS "return current" from the radials, ground rod, the air, and the counterpoise. Vertical antenna manufacturers include a ground plate or ground "screen" around the antenna base to provide a low impedance path for return current from what's acting as "ground." Depending on the earth isn't good enough here. One idea: instead of a narrow flange to hold the 3/8 inch bushing for the "stick," replace it with an approximately 3/16 inch thick round disk (or square plate) of copper, aluminum or brass. Attach the radials around the outer edge of this "base plate." This will reduce what's referred to as ground loss. The second approach (also borrowed from makers of "real" is pay attention to the "skin effect" at RF frequencies. The coax center conductor provides a fairly direct path to the bottom of the antenna element. But the coax shield also carries RF current (see first approach above). Look closely at the path from coax shield to the radials and ground rod. Part of that path is THROUGH some metal parts. But RF doesn't readily travel THROUGH what at DC is a good conductor. Instead it travels on the surface and therfore maybe around the edge of parts of the mounting system on its way to the radials and ground rod you took time to install. Remember that differential mode current can be found on the outside---not the inside---of the shield of coax where a balun was left out. This current never makes it to the inside surface of the coax shield---why, because of the skin effect. It's better to attach the radials and ground wires to the BOTTOM of the mounting flange, square or round base plate, or whatever. Make the skin effect a ritualistic part of your total portable antenna system design.

You could use a Nano VNA if on a budget, they can be used as an analyser, and they are the size of a small mobile phone.

I'm looking to set up a portable similar to this but have no idea where to find the mounting plate that attaches on the camera mount and provides an attachment point for the antenna and radials/counterpoise. What are those things called? It's hard to do a web search for a thing that doesn't have a name.

Hi Peter, as I own a Buddistick, I must admit to having issues re high SWR, tuning and noise levels. The Buddistick has been through an analyser and pins positioned correctly by better hams than myself. Having watched this video, I've invested in the aforesaid copper earthing rod and 3 ground wires, and the ferrite ring. Would you also recommend a line isolator or will the ferrite do the job ? And or Should the counterpoise wire included in the kit be disregarded as I can't recall you mentioning the Buddistick Counterpoise in this broadcast. Thank you.

Hello Rob. The ferrite core should do the trick OK. The original ground wire can still be used if you wish. The more the better. But I tend to use around six radials about 5m long. In that situation I have found that adding the longer suppled radial makes no real difference. 73 Peter.

I wish I would have received this advice when purchasing the Buddistick. Toroid Rings and Grounding Pole additions were never advised for this product to obtain suitable performance from the buddistick. I'm wondering if the Buddipole Company are aware of the issues ?

From what I’ve read, if possible, elevate them at an angle downward and stake them above ground. This is what I do with the three radials cut for 20m elevated from about 6ft down to about two. I use an Chameleon MPAS 1.0.

Hi Darren. Generally a few turns of cable around a torroid core is better than a ferrite clamp. I use 240 - 43 rings which are karge enough to permit a PL-259 plug tp oasis through when adding the coax winding. 73 Peter
