I am not going to be a proponent of the Buddipole system, nor am I going 
to be an adversary.

In other words, the Buddipole system works well, and the standard system 
will tune to 15 through 10 meters without the added inductors.  For 
bands below 15 meters, some inductance is added to lower the resonant 
frequency.  Those inductors do reduce the efficiency, but it is 
proportional.  The amount of inefficiency on 20 meters is small, but on 
30, 40 and 80 meters, it increases substantially.

For those doing SOTA and operation from places where there are no trees 
or other natural supports, the Buddipole is a real salvation, especially 
on 20 meters and above, but below that,  inefficiencies creep in and it 
becomes a physically small antenna unless extra measures are added.

One of those extra measures is to add wire to the tips of the extended 
buddipole whips.  Clip on alligator clips or others can be easily used 
to extend  the antenna and increase its lower frequency/

OK. please let me be clear -the Buddipole is a good system, but does 
have its limitations.  For those of you who have home stations, a 
resonant dipole at 40 meters and below will outperform the Buddipole.  
For those who do not have that as a possibility, then the Buddipole is a 
good alternative.

My reference is to use a 32 foot telescoping pole with the antenna 
deployed at the top for a 40 meter and below antenna - the center is at 
32 feet and it is usually strung as an inverted Vee in the field.  The 
lengths of each can vary from a resonant length to whatever the height 
and length can provide.

Other than the the pole height, the rest is up to you.  Put up a 
resonant dipole with the feedpoint at the center, or put up a vertical 
with counterpoise wires,it makes no difference, you have an antenna that 
can communicate.    Cost is the price of the pole plus the cost of the 
antenna wire and feedline -nothing more, and you get to experiment with 
many different antenna configurations.
