"It took 5 minutes to set up with the Faraday Strip and it tune 1. 05:1 on 20m. Then the POTA activation this day end with 35 QSO in less then 2 hours. It make it ideal for public park usage, fast to deploy and the same for dismount, this antenna will become my 1st antenna system for my next POTA ops this summer. 73, de VA2OPS"

Great kit
"I've started experimenting with this as both a ground mounted vertical and an elevated vertical with tuned radials. It's just a very simple way to get a resonant antenna on the air quickly. A lot of my operating is QRP, so running this elevated with a couple tuned radials makes sure that I get as much of my 5W coming off the radiator as possible with a low take off angle."
— Todd D. (5/5)
Cha-BV antenna
"I recently purchased a CHA BV, I have had a chance to use it a couple of times and it has worked very well. My favorite features of this are the quality, performance and most of all the ease and speed of the setup. I own several other portable antennas and this is my overall favorite!!"
— Corry W. (5/5)
Excellent
"Easy to setup. Contacted Chile for San Francisco California"
— Marco (5/5)
Elegant Well-Built Portable Antenna Solution
"I am delighted with this elegant and well-made antenna! In a recent POTA activation it performed nicely on the two bands I used. I like the simplicity of setup, and the ease of tweaking for optimum performance. Setup takes 10-15 minutes and retrieval about the same. I have used many, many portable antennas in 60 years of ham radio. This spike vertical is easily the best of them for most applications."
— David J. (5/5)
Loving this kit!
"Bought it as my first leap into a proper resonant antenna, and for use while camping or other outdoor activities, LOVING it so far! Everything is really well made and so easy to just toss into a backpack!"
— David S. (5/5)
Great System
"WOW! What a great antenna setup with the M25 coil combined with the stinger counterpoise system. My SWR flatlined at 1:1 on 40 meters and I was booming across Texas on a RACES net check-in."
— REX (5/5)
Extraordinary Performance
"I have built many wire antenna's including verticals and tuned them for resonance. I thought that by building my own I could match the performance and ease of setup that a commercial antenna like the BV could do. Yes, I have had success with wire antenna's and continue to use them at my base. However, I bought the BV and it exceeded my expectations! Ease of setup +5 stars. No tuning for 40 or 20 meter bands, +5 Stars! Quality of the build over cheaper import copies, +10 Stars! It has been well worth the investment to use with my portable station for POTA and operations at home. You won't regret the purchase of this antenna system. KD5SMF- Tulsa, OK"

Great quality
"Solid quality and well built. It can be pricey, but you certainly are paying for great quality that should last."

Q&A
Band-adjustable resonant portable vertical
A direct, field-adjustable path to resonant vertical operation
Make every inch of radiator work for the band you chose.
CHA BV is a straightforward resonant vertical for operators who want to change bands by adjusting a physical radiator—not by hiding the antenna behind a wide-range matching network. The standard SS17 system covers 40 through 6 meters with the included 40/30-meter coil and four 12 ft 6 in radials.
Choose the SS17 or SS25 package to match the desired height and band plan. The optional LZ SLOPER adds a separate inverted lazy-L path for 60, 75, or 80 meters; it is not the same electrical configuration as the bare vertical.

Documented ways to use this system
Each card describes a complete guide-controlled path. Connector fit alone does not create another supported configuration.
SS17 vertical
Use the guide's band-specific whip length. Add the included medium coil for 40 and 30 meters.
SS25 vertical
Use only the SS25/M25-coil paths documented for the selected BV package and band.
Optional lazy L
Add the 60 ft LZ SLOPER wire for one resonant 60, 75, or 80 m configuration at a time.
Band change: adjust the SS17 or SS25 radiator length and the applicable radial length exactly as the BV guide describes. PRV/MCC tuning rules do not apply to BV, and the SS17 and SS25 coil systems are not interchangeable.
