ButterNut HF9V / Isopole 440

Today I went to the MTARA’s Hamfest located in Springfield MA looking for Anderson power pole items. Since I have not been to a “Hamfest” in 6 years or so, It looked rather small. Last one I went to was MTARA’s fest when It was in Amherst and It was 4 times the size. After talking with some people they told me that this “Small size” fest is actually bigger compared to the past couple of  years. That’s a good sign that there is more interest in Ham Radio in the Western Mass area. Hopefully it grew.  While at the fest I saw a box with some aluminum tubing and aluminum coils sticking out the top and thought it was a butternut antenna. After talking with the seller it was indeed a Butternut but That’s all he knew. He didn’t even know if it was a complete set. He was asking $60 I talked him down a tad because of the uncertainty of it being complete.  After getting it home and doing a quick assembly, It’s a complete used ButterNut HF9V with the 75Ohm matching cable and manual. So I am quite pleased and I hope this antenna performs better than what I was originally going to purchase (S9’s 43ft Verticle W/ 4:1 unun).

Can’t wait to get this project going.  Hopefully the 90Ft of RG-8x will reach. The only fabrication I plan on doing to this is making a Stainless Ground Radial plate to mount the ground radials onto.
At the MTARA’s Hamfest I also picked up a ISOPOLE for 440mhz. I purchased to see If I can duplicate the antenna. It appears to be either a 1/2″ or 5/8″ Solid Aluminum Rod with a couple of 0.030 aluminum cones with a small lock seam (Pittsburgh lock?), Fiberglass insulator, Hose clamps and N-Type connector. I have not really looked at it other than putting in my attic just to see how it performs compared to my other 440mhz Antennas.  Quick test shows that it performs a little bit better than the Copper cactus and my Dual band OSJ-Pole.  Once the weather get’s nice it might end up on the roof.

Last stop I made to the Hamfest was to HCRA table and purchased a membership. I like to support the local ham clubs so this was the day to do it.

    1. Thanks. Saw your picture in QST this month for the Rookie roundup. I laughed when I saw the photo and I was saying “Gee, I was just talking to him last week”

  2. Hi !

    Boy I have a badly damaged 2nd hand Isopole 440, too !
    Can you have some measures of it ?
    Cone dimensions, spacing and so on…
    ( and where the “N” Connector is located ? )

    TNX Friend !
