My Buddy and Me. MY BUDDIPOLE experience!
I purchased
my Buddipole Deluxe Antenna almost 16 years
ago. This blog is not to endorse or
oppose any aspects of the Buddipole antenna system but simply my experience in
using it.
Over my many years in ham radio, I’ve owned only three commercial built antennas. At the time I purchased my Buddipole antenna I owned a SUV and was impressed with its small footprint. I didn’t use my Buddipole that much before going car-free after three years of it’s purchased. Most of my Buddipole use after going car-free has been for Field Day.

When I discovered Parks on the Air in 2020, it was time to bring my Buddipole into use other than Field Day. For many of the years of owning my Buddipole, I was never able to get any decent SWR readings on all bands. Nothing lower than 2.5:1 on any bands 40 – 10 meters in the Dipole configuration. When I retired in 2016, it gave me more time to enjoy ham radio. During the pandemic shutdown, I took the opportunity to figure out what I was doing wrong or why I couldn't get a decent SWR reading in the Dipole configuration.
I re-read the operating manual, enlisted help through inquires on social media, joined the Buddipole users group, purchased a Nano VNA. Still nothing under 2.5:1 I was at my wits end. I had invested several hundred dollars into my entire Buddipole Deluxe Antenna System with all of its ancillaries and was ready to sell it.
Before getting materials to package my Buddipole to sell, I re-read (KI6AWK) David Haycock’s “Brief Guide to the Buddipole Antenna System. I decided to try setting up in a vertical configuration for 40 meters and trimming some speaker wire for radials and using the Triple Ratio Switch Balun. I was thrilled to be able to achieve a SWR down to 1.5:1 on 40 meters using the TRSB with 3 radials, 9.5 foot whip, two standard 22” Antenna arms and the 18’ mast.

Then I decided to try setting up the antenna in a 20 meter dipole configuration without the TRSB using standard whips and antenna arms. I still could not achieve a SWR lower than 2.5. So I decided to check the coax I was using which came with my system. I checked with my Nano VNA and no problems. As I was disconnecting the coax from Nano VNA, I looked down the barrel of the BNC connector and noticed the center pin of the coax had disappeared. Further examination showed the center conductor of the coax had pulled away from the coax braid. No wonder I was getting inconsistent SWR reading with this coax.
After
placing a new BNC connector to the coax, re-setting up Buddipole in a 20 meter
dipole configuration, I got a 1.15:2 SWR reading without connecting it to my Nano
VNA. Deciding not to press my luck, I disassembled my Buddipole for another
day.
Now that I was able to assemble and get my Buddippole to operate in the manner for which it was manufactured, I pulled the “For Sale” sign from it. Additionally, I found another article from (KI6AWR) David Haycock. “More on Buddipole Tuning”. This article gets a little more in-depth with how to adjust for the resonant frequency, feed point impedance and provides a table to easily fine tune the Buddipole in a dipole configuration. From that day forward, I've never had any issues assembling my Buddipole Antenna System in any configuration from 80 - 2 meters.
NOTE:
I have found the best way to fully appreciate and use the Buddipole Antenna
System is with the use of an Antenna Analyzer.
This tool is invaluable in fully enjoying the capabilities of the
BUDDIPOLE.
Over
the years I’ve used several different configurations. L-Shape, V-Shape, Dipole,
Vertical, 6 Meter Yagi, and 2 Meter J-Pole.

With the above types of results I’ll be using my Buddipole Antenna systems quite a bit more
Buddipole:More on tuning KI6AWR
by David Haycock, KI6AWR
Buddipole is an antenna system with many
combinations and ideas to get a signal out in the air
The Buddipole, the Buddistick and the
BuddiHex
The BuddiHex took 10 years of iterations
and design ideas to come to production with its massive wait list
Buddipole offers spare parts and
accessories to make your deployments easier and faster on any ham band
First, READ THE MANUAL, as its not a
traditional dipole but a slightly Offset Center Fed Dipole. This brings the
antenna impedance closer to 50 ohms due to its shorter antenna length. For a
10m dipole it would be deployed like a regular dipole. However, one side will
be a bit longer or shorter and its tap point will be different than the other
side. No need to understand it just follow the instructions and you will be
fine.
Yes, an antenna analyzer like the
Rigexpert 230 Stick will be ideal as is the iPortable meter. I use both
depending on what I am deploying. Its a bit pricey but I have had mine for 10
years and replaced the battery twice. Its an ideal size and does exactly what I
need ….quickly in 3 seconds be able to check the SWR. I just got the RE Stick
and I am excited to try it out at the parks.
Ok always ensure you use the guys on your
tripod ALWAYS as the wind can knock it over
Tip #1 Get longer whips to replace the
standard 5 and half foot ones. Longer whips means more signal on 20m and 40m.
The 9 and half footers are a nice add on to your kit

Tip #2 Get additional arms to increase the
length between the VersaTee and the Coil to increase signal output and allow
the ablity to make a beam
Tip #3 Get the TRSB Triple Ratio Switch
Balun as it will allow its use as a common mode choke to keep RFI out of the
coax but also to work as a transformer to up convert the impedance ratios to
match at 50 ohms. Compromise antennas can be very capacitive (remember the LC
circuits on the ham exam) but the big coils on the Buddipole compensate but the
resonace impedance can be 12.5 ohms so we need to bring it up to 50 ohms using
the 1:4 position. A 9:1 balun takes 450 ohms and drops it to 50 ohms.
Trust me, I tried to play around and make
my own but I did get Alex Biocca’s kit but since I have too many Buddipole kits
I needed another one. I should have gotten two so I can use it with my Super
Antenna MP1 or homebrew whips.
Tip #4 Just get the Deluxe Kit at a Dayton
Special price as the 18 ft mast makes a big difference. Try to get every
antenna up that high as a 1/2 wave above ground is the way to go for best
radiation performance.
You can get the painter pole adapter from
Budd and be all set up with a Big Box store special Painter Pole $40
The Buddipole team is happy yo mix and
match components with other brands as needed as its all about having fun and
making QSO

Bonus Tip: You will get a Mastwerks
eventually so get it now
See the Dec 2022 QST for my BuddiHex
review
POTA with the BuddiHex is the next level
of operations think being an Extra class or Advanced
