[TowerTalk] Tying 80 and 160m radials

[Rod Greene]

Ignacy,
Tim is correct!
In the 1980s I had a home brew 4 square on 80M and I had it installed and centered over a field of 100 radials. There were 50 radials 66 ft long and 50 radials 100 ft long and each were nr 12 copper wire. All were bonded together at the center. This system played extremely well. I worked many times into EU from my QTH in ID. Made DXCC ON 80 too. 

Good luck and 73, Rod/w7zrc

Hello Ignacy:

Strongly connected is the answer. When it comes to radials - more is always
better.

A tower is shunt fed for 160m and will be used to support 4 sq for 80m. A
question is whether the radials systems for 160m and 80m should be
strongly connected, weakly connected or disconnected.

AC0C has 160m radials buried and 80m radials on top of grass. They seem to
be disconnected. He has a good signal.

ON4UN writes that mesh for both bands is OK and also that a single elevated
radial for 80m over 160m radials works very well. He has a good signal.

If 80m radials are connected in the middle as recommended for DXE 4 sq,
that connection ties into 160m radials in the center.

One answer is it does not matter as long as there are sufficient number of
radials. Any practical experience?

Ignacy, NO9E
