Several years ago I built a 2 wire Rhombic below the Houston Rhombic with the idea of phasing the two together. I did not do my research properly, I should have understood that stacking Rhombics results in a very narrow pattern with almost no sidelobes. This was used to good effect in earlier days to reduce multi-path errors on Point-to-Point circuits using RTTY.
The results for me were that I was only able to contact Brooklyn, New York and no other stations could be heard…
The antenna has been dormant ever since until now. I rewired the lower array to point in the reverse direction of the Houston Rhombic and I call this direction Tehran, it basically gives me a good shot to Scandinavia and Russia.
The first QSO with the TEHRAN Rhombic was made with a very interesting station.
Vic, R6AF/P had a booming signal from Sudzhuk Island in the Black Sea and he replied on my first call.
This island is near Novorisssiysk and I may have glimpsed the island with my own eyes when I drove through the area during my UN service a long time ago as part of a convoy from Zagreb, Croatia to Sochi.
I now have 7 Rhombics functional, Buenos Aires, Houston, Tokyo, Perth, Tehran, Cairo and Durban, with a new Rhombic in the final stages of construction – Quito.
