New Equipment – QRPGuys Portable Tri-Band Vertical Antenna

Even though I’m in the middle of figuring out the build of a shortened end-fed half-wave antenna, an improvement on my current EFHW setup, I’d had my eyes on various vertical antenna solutions for a while, even though they’re not as efficient as a full-size antenna. Recently, QRPGuys released a new vertical antenna kit for portable ops, and I couldn’t resist trying it out.

I recently put together a new antenna, the QRPGuys Portable Tri-band Vertical.  I’ll be writing another post about this antenna specifically, but it’s a new product based on Joe Everhart N2CX’s design, published in a recent QRP Quarterly.  It’s a quarter-wave vertical on 20 meters, and uses switched inductors to work 30 and 40 meters.  It’s pretty lightweight and compact, and seemed like it might work well on summits without space for a full-size antenna.

I wanted to get out to an easy summit to operate Winter Field Day for a couple of hours. I ended up only getting about an hour, but it was a good hour! I’ve done this summit a few times, but this is the first time it’s in my blog. It’s a short, fairly easy hike, and not too far of a drive from my house.

My wife and I were visiting Joshua Tree National Park for our tenth anniversary.

I wanted to get in one final SOTA activation for the year, and planned on doing it the week between Christmas and New Year’s eve, but had come down with a nasty cold. Even though I still had a cold, I decided I’d do it on the very last day of the year.  Having seen that Jeff, AA6XA discovered this hike could be done on public land, I couldn’t resist the opportunity to get this one done.  It’s an exceedingly beautiful hike into an isolated part of the Diablo range.

I’d been wanting to do this activation before the end of the year, but kept putting it off because it’s easy, but also kind of a long drive for something that looks so close. It’s easily visible from my house on most days, being the only summit around with several big telescopes.  But it’s an hour or more to drive there.  This one had several firsts for me! First European DX—Spain. First aeronautical mobile contact. First time getting more than 50 QSOs in a single activation. My timing turned out to be quite good!

I was over in Santa Cruz for work, so decided to make a “quick” detour on the way back over the hill so I could activate this summit. I’ve had my eye on it for a while, so I posted an alert on SOTAWatch and squeezed in some time to do it. The detour isn’t actually very “quick,” but it’s within reason.

LNR Precision MTR-3B Power Test

I’ve had the Mountain Topper for a couple of weeks now, after having wanted it for a long time. I’ve been really happy with it, and I’ve even already done three SOTA activations with it and lots of SOTA chasing from my back yard. One thing I noticed when doing my pre-purchase research is that not many people report on the power output (probably because it doesn’t matter that much). Well, I got curious! Here’s my extremely inaccurate and non-scientific report.

Route: Park near summit, short walk to top
Dogs: Yes  Toilet: No

Out of the three summits we did on this trip, this one was the easiest. Parking a short distance from the summit, it’s an easy walk up a gentle grade. There are abundant places to set up antennas and the summit area is fairly large. There’s even a little bit of cell service! After the (mis)adventures of the earlier summits (4850 and Santa Rita Peak), it was nice to have a little break.
