80m Buddipole Dipole

Buddipole Sunset


We spend a lot of time on the lower bands, in particular 40 and 80 meters.  While the standard Buddipole kit of parts includes everything needed for a 40m vertical or dipole it falls short on 80m unless you have an antenna tuner and then its not very efficient.  As you proceed with low band Buddipole configurations it's important to keep in mind the lower the frequency the more narrow banded the Buddipole will be due to it's physically short length.

Our Buddipole title photo is of this NVIS antenna project setup on a trip to Washington State's Okanogan National Forest.

To build this antenna you will need several parts that are not included in the Buddipole standard kit of parts.  You can order the addition parts on the Buddipole website.  Most notably a pair of low band coils and an extra set of 22" aluminum arms, and the TSRB.




Low Band Coils x2

11" Arms x2

22" Arms x4

Telescopic Whips 5.5' x2

Mast 16'


Guy Kit

Coax w/BNC for TSRB



Do the same for both sides of the dipole.  From the Versatee install an 11" arm, then a low band coil, then two 22" arms, then finally a standard telescoping whip fully extended. 


The TSRB will need to be connected to the Versatee, to aid in strain relief I like to hang the rope loop on top of the TSRB on the blue lug of the Versatee.  Using a velco strap over the coax connection at the base of the TSRB is also recommended.


Depending on the guy wire solution you have choosen you can either tie the lines to the Versatee directly or if you are using the BUddipole guy system attach the velcro guy strap just above the highest knuckle of the mast.  Guy rope is required at all times for this antenna.




TSRB = 4:1

Tap Red Coil @ 40.5 Turns from female end

Tap Black Coil @ 39 Turns from female end

Whips fully extended

Mast fully extended



Frequency match 1.2:1 @ 3.968MHz, Tap the red coil at 40 turns to shift match to 1.4:1 @ 3.975Mhz


Very narrow banded but really good signal reports on NWCC net and WARTS net.  5-9 report from Maltby to Yakima during poor band conditions.  On several ocasions we've been told this antenna has had the best signal on the band during various nets.


This antennas receive capability is comparable to our 80m double bazooka dipole with less than an S unit difference.  It may actually outperform the bazooka on transmit due to the good match of this antenna without a tuner.


Typical directional characteristics for a dipole



To achieve 40.5 turns count 40 turns from female end then follow the 40th turn to the backside of the coil and place the clip.


The idea for this configuration came from an 80m vertical I was experimenting with, it occurred to me that if the configuration I was using works vertical, what would happen if I turned it horizontal and added a the second whip.  Changes were needed in length, coil taps, and TSRB settings but in general the idea worked, the resulting antenna gets far better signal reports and is also much stronger on receive than the vertical.
