At the 2m band only a whip for each side is sufficient to operate? Sorry my english is very poor but I would like to thank you very much for any help. 73/51 from PU7AIK Crezivando JUNIOR from Maceio Alagoas BRAZIL Hi

I don't know much about the buddipole, except that it's just an inductively loaded centre-fed dipole. Dipoles work best >= a half-wavelength above ground. I guess the buddipole has a movable tap on the loading coils, and positioning will be very critical. Even half a turn either way will probably put the antenna out of resonance. Likewise the extendable end parts, a few mm either way, and you get a mismatch. It should be possible to get a reasonable SWR though. On 40 metres, this antenna used horizontally would need to be much higher to raise the feedpoint impedance to around 50/75 ohm. One-half of this antenna fed against a good ground should work reasonably well as a vertical. You'd get a much lower radiation angle for DX this way. On 40 metres, the bandwidth will be very narrow.

Its fun to tune it though at 40 meters I also could not tune better than 2:1 swr . Am using it for last 15 days only . However , last night I didn't adjust (spread / opened) the tripod properly and found my antenna fallen down with one whip broken in 2 pcs and the other one bent !! 73 , Rajeshree , VU2LAW Hi ,
