Portable Antennas...

I've had several people email me recently asking what antennas, other than my hamsticks, I use for POTA and portable operating. It must be admitted that over the past few months I've got lazy and only used the hamsticks...mainly for the convenience.

There are several different portable wire antennas in my rucksack.  The following are a few of my favourites, but please remember, antennas are like opinions...everyone has one and everyone has their favourite.

A few years ago I was having some trouble getting a Bandspringer Midi antenna I had bought from Sotabeams to tune up with sufficiently low SWR....the SWR I had was over 25:1 over all bands and nothing I did would change that fact.  It just wasn't happening, and the thing was, to me, completely unusable so it was put away in a drawer.  Shortly after this I was watching a video of Steve, WG0AT, operating SOTA from Mount Herman in Colorado, and I noticed he was using a simple wire antenna.

I emailed Steve about it, and he told me it was a 41' radiator and a 17' counterpoise, and with his KX2 he could tune it on all the bands he needed.  No balun required, just a binding post to BNC converter, and you're in business.  That afternoon I took the Sotabeams antenna and spent a few hours doing surgery, and transformed it into what I now call my "WG0AT Antenna". It works like a charm and I have made hundreds of contacts with it on all bands 40m through 6m.

Probably the most used antenna in my collection is a 40m EFHW.  This was built with a LnR Precision transformer that I found hiding in a drawer one day.  This antenna works on 40m through 6m and I have never had any bad SWR issues with it.

Just 63' of wire, no counterpoises, and you're on the air.  I used this antenna at Chillycon this year as my campsite antenna, and made over 200 contacts with it all over Europe and North America. A great antenna.

My 20/40 linked dipole has also seen a lot of use in the past, but not so much lately.  This was built from plans found on Google, and it does match and work very well on 10m/15m/20m/40m. It is a bit of a pain to put up, but it is a solid performer. I plan on re-making this antenna out of lighter gauge wire as at the moment it is far too heavy to carry.

It is well worth the time and effort to make one.

The Packtenna Mini is the only store bought wire antenna in my possession.  It works very well.

This is a 9:1 transformer and 66' of wire.  The instructions state that you don't need a radial....but....I find that I must use ground radials with it as well as an RF isolator to get the SWR down to were I want it.  I have made a set of three radials on a large alligator clip that I use with it.

To be very honest, while this antenna works extremely well, it doesn't work any better than any of my home-brewed antennas, and it wasn't cheap to buy either. 

So there you have it, my wire antenna collection - and my thoughts on them.  I very rarely use them for POTA activations these days as they all need a portable mast or a tree, and in the crowded conditions of some parks, it's just far easier, and safer, to use the hamsticks.

Stay safe out there!

Did I Hear The Bands Turn Off?...

It was a great morning up on Fort Henry Hill.  It's a very quiet RF site now that the dozens of plasma TV's they had installed in the information centre have all broke and been removed.  The down side was the temperature which sat at -7C, not including the wind chill factor.

Todays propagation, not spectacular by any means, was:  SFI=92, SN=20, A Index=4, and the K Index=1.

I managed to work 17 stations on 20m, including CU3HY in the Azores, and KN6KI in California.  There were a number of repeat offenders who seem to find me every time I activate, and I'm very grateful for them.  

About 1500 UTC the bands instantly went quiet, the signals just disappeared.  There had been a great deal of very deep QSB on 20m, but at least you could hear something.  I spun the VFO several times across 20m, 40m, and 17m, and heard nothing, just static.  The bands, it seemed, had turned off.

I'm hoping that they turn back on in time for another couple of POTA activations tomorrow.  My original plan was to stop activating this year when I reached 100 activations...now I plan to keep going until the weather makes it uncomfortable to activate.  So I'll probably get about 10 more.

Stay warm out there!

A Milestone has passed...

A year ago this month I decided to get involved with the Parks On The Air (POTA) program, and I have absolutely had a blast doing it.

Yesterday, November 26, I achieved my 100th park activation this year, and have managed to put 2856 contacts in my log carrying out activations or hunting parks.  On top of this I have actually started to get my money's worth out of my KX3!!

Also this week my new powered speaker from West Mountain Radio arrived.  What a difference that has made to operating the KX3.  I can actually hear things properly now.  The signals I am hearing are now crystal clear, and there is no more of the famous KX3 distortion.

This speaker is a game changer for people, like myself, who have hearing issues.....and I have way too much time flying very noisy Chinook Helicopters.  And of course, as we get older our hearing gets worse.  

I've a few more activations to go before the snow starts to fall (which it did today for a short time).  It's definitely getting colder, and sitting in the back of the van doing an activation isn't the most comfortable of places these days.

The KX3 and new speaker set up in the van.

Stay warm out there!!

Great Morning on the Bands...

It was a cold morning here, just -1C when I left to activate the Frontenac Biosphere, VE-0023.  I didn't expect to have much of an activation, I know I'd get the ten required contacts, but I assumed it would be just the normal chasers.

How wrong I was.   The propagation this morning was SFI=78, SN=22, A Index=5, and the K Index=1.  The radio in use was my KX3, and I had a 20m hamstick on a mag-mount on the roof of my van.  This has been my normal setup for a few months now, and it never ceases to amaze me just how well the Hamsticks perform.  Today was no exception.

So with 10 screaming watts into the hamstick I worked Mike, CU3HY in the Azores, Jean, F4ILH in France, Rodolfo, I4RHP in Italy, and Bryan, KP4M in Puerto Rico.  I was just amazed as the DX stations called me, I never thought I would be doing cross-Atlantic contacts today.  It was just amazing.

Here's the contact map from today:


Looking forward to more of this!!

Good Results On The Bands...

The last two days I have taken the time to do a couple of POTA activations.....now there's a surprise.  But, I really felt the need yesterday, November 11th, to get out and operate as I really felt my Dad's presence.  He was a Signaller and a WW2 Veteran, and although he died 28 years ago, very rarely does a day go by when I don't think of him.  

Propagation wasn't too bad, SFI=87, SN=37, A Index=8, and the K Index=2.

I packed up the KX3 and Hamsticks and made a few successful calls using his, and now my call, VE7CVQ, and then spotted myself on the POTA app using my VE3FI call.  The results on 20m were an amazing 24 contacts in 19 minutes.  Here's the contact map below:


Today, Friday, I decided to go and operate after my morning walk.  I ended up at Lemoine Point and put 32 contacts in the log in 24 minutes, all on 40m with the KX3 and Hamsticks.

Propagation today was: SFI=84, SN=39, A Index=4, and the K Index=1.  Here's todays contact map:


Today was my 92nd POTA Activation this year (I'm shooting for 100) and I've put 2,632 POTA contacts in my log since January 1st.  Every time I do an activation I am constantly amazed just how well the KX3 and Hamsticks work together.  

It was a good couple of days, and I'm glad I got out to operate.

Back At It...

It didn't look a good day to play radio today, this morning the propagation numbers were:  SFI=84, SN=28, A Index=69, and the K Index=3.  It was pretty noisy and there was lots of deep QRM.

By mid-afternoon the effect of the last CME on the propagation had started to settle down.....so it was off to play POTA.

It's a short drive from my house to Lemoine Point, VE-5141, and I set up the KX3 and 20m Hamstick upon arrival.  It took 27 minutes to get 25 contacts in the log, including EA1AF in Spain, W6KC in California, and K7SEN in Arizona.  I did not expect to make half the contacts I made, it was amazing the way they kept answering my QRZ.

I'm hoping that band conditions hold up all weekend so I can get a few more activations in.  I've done 87 activations so far this year, and my goal is to complete 100......13 to go!!

Here's a look at todays contact map....

K Index = 7 !!!

It's not often you get to see a K Index of 7 !!!!  I don't imagine the bands are going to be very good for the next few days.
