SAY5-9
This is Yagi for 10-12-15-17-20 - 2 full size elements for each band.
All 5 active elements are connected by a phasing line from a square aluminium profile.
Full info about SAY5-9 type here.
View from 46m tower
Antenna on 12 metre mast (the mast is home-made).
SAY5-9
SAY 3-16
This is Yagi antenna with 16 elements for 3 band, active elements phasing same as SAY5-9 antenna.
SAY3-16 is: 8 full size elements for 10m,
4 full size elements for 15m, 4 full size elements for the 20m band.
Full info about SAY3-16 type here.

SAD 4030
This is full size Rotary Dipole for 30m and for 40m bands.
But my SAD 4030 is rigidly fixed at height of 47,5 metres.
A direction of petals - NA in one party, the AF (almost) in another.
Full info about SAD 4030 type here.
47,5 up is very fine for it antenna!
Dipole after Dec'2014 snow storm.

1/4 wire Vertical for 160m
From idea before realisation.
Idea in MMANA software
3D MMANA
Such decision for the radiator has allowed to make a wide strip with SWR=1.
Box with DXEngineering vertical feedline current chokes.

WireSpear (WS) antenna for 40m (bi-directon to EU and NA)
Idea this antenna = Alex UA4WI. This is a bi-directional 6-elements antenna.
My WS directions
Ant top on 47mH, bottom=12mH
Actual real SWR
WireSpear antenna for 80m band
Idea this antenna = Alex UA4WI, see MMANA file click here
This is a bi-directional five-elements antenna. I'm testing it from the middle of Sept'17.

WireSpear antenna for 160m band
The next generation - The first in te world the WireSpear antenna for 160m.
Many thanks to Alex UA4WI for the idea and help.
The file for the MMANA program can be downloaded here Everything else is clear from the diagrams and pictures, photos. The direction of radiation differs from the WS-antenna variant by 80 m because for 160 m I did not have the height of the suspension of the upper point.
But the result of the work is very good! Such an antenna can be hung in urban conditions between two buildings, one of which will be high-rise.
