Ham Radio on Mt. St. Helens Summit

- *UPDATE* I took this antenna to the summit of Mt. Adams (12,281ft) and was able to check into a net through a repeater in Pullman, WA (which was 211 miles away) using only 5 watts.
When I climbed to the summit of Mt. St. Helens, I brought with me my IC-T7H and a lightweight 2m yagi antenna that I had built. I then proceded to see which repeaters I could hit from the summit. I then decided to try my luck with 146.52 (the national calling frequency). To my surprise, after calling CQ only once, I immediately was flooded with several people returning my call.
To see how to build the antenna visit: • 2m Backpacking Yagi
This is a lightweight antenna designed by KD5IVP that I found the plans to online. It's simple to build and lightweight. It is for use on the 2 meter band. This video is my explanation on how to build it. Further details on the design and a slightly different way of constructing it can be found at:

Excellent! I now have a project for the weekend.
Thanks for the great videos on this Yagi..

I will be heading up to mt Saint Helen's in April so should being my 2 meter radio :)
Great job on the contact.
I enjoyed seeing this!
This is cool! The stuff I like to do as well.
Keep'em comming! 73's from LA4CIA
lol, I know the guy Tom, n1bec that you talked too. I talk to him on a reg basis. that looks like a really good spot to have a vhf qso party. anyway, just to let you know, i am mobile every day for atleast 11 hrs a day, and tend to be solely on 146.52. I run QRO though, so I tend to shake a lot of people out of the bushes, but not like elevation like that can do. 73. ke7utp
thanks for sharing!
2020 Anyone?
I think you need to make a stand for it so it's not shaking around as much, even a high walking stick would help your stabilize it.
Over 200 miles with a tiny handheld Yagi and a 5 watt handy talky! Amazing
bring a tripod and you wont have to hold the Yagi.
Great antenna, great video I was searching for something to put in my pack. it looks like it works good. it may work even better vertically polarized. KC7UPZ
Hi, nice video and nice contact it's a pleasure

There is not really any need to state the frequency. That is redundant. If they are listening they know what frequency is being used.
I know yours is a 2yr old comment, but for others reading - stating the frequency is NOT redundant, it's common courtesy. Most radios these days have a scan function that many hams use quite often to scan multiple frequencies for traffic. While the radio does pause when it hears something, it continues scanning briefly afterwards (depending on how it's programmed). So, if the person receiving doesn't glance at the radio fast enough they can miss the frequency your calling on and therefore can''t respond to you unless you call again. By, stating your frequency this is avoided. Hope this has been helpful. 73.
To add to the previous reply, stating the frequency not only alerts hams which frequency to respond on, many hams will make simplex calls on 520 a priority to respond to.
If I heard someone calling CQ on 520 and they said they were perched on St. Helens' summit, I'm much more inclined to respond to that rather than general repeater banter. -Not redundant at all. Pedantic, maybe...
