Thanks for everybody for good comments,
They are quite in balance with the information I have red from net.

The antenna which I am planning is for portable use and should be
easy to erect and transport.

Your remarks led me to some comments:

- Yes the efficiency on 80m may be too low, because of small size.
- Adding center extenders could help but then 75m hamsticks are out of 80m
band
- By using 40m hamsticks and maybe center loading coil and extenders tuning
to 80m possible?
- Then also operating on 40m without extenders OK
- 80 operation only needed for domestic qsos, no DX
- On 30m and 20m hamstick dipole would work OK

Any comments on these?
