Cheap vertcals
I want to put up some inexpensive vertical antennas for 20 thru 80 meters.
They will be temporary not being there more than 3 years. Would EMT conduit hold up this long |

But, EMT is a 'soft' aluminum and will require guying and/or other support. It is soft so electricians can bend it around corners. |

It comes in different sizes but they are not a tight fit from one size to the other. It would possibly last 3 years if you are not too close to salt water. |

There is also such a thing as aluminum electrical conduit. I am using an 8 foot length as an antenna mast that measures about 1-7/8 OD. There is a tribander directly above to rotator, a 6 meter 7 element beam at the top, and a 2 meter 10 element in the middle. It has been up 7 or 8 years, gone through high winds, and has shown no signs of bending or corrosion. It is fairly soft, but has thick walls; still, a lot lighter than steel. Tam/WB2TT |

Tam/WB2TT Yes there is aluminum rigid conduit made..But it is not cheap. |
