Antennas

Portable Antennas

Antennas you can carry, set up in ten minutes and take down before the wind picks up, for parks, campsites and the tailgate.

What makes a good portable antenna

Quick to deploy: if it takes an hour to put up, you’ll stop bringing it.
Light and packable: it should fit in a bag with the radio, not need its own trailer.
Forgiving: it should work reasonably well on uneven ground, near trees, or off the side of a truck, without perfect radials or a perfect height.
Wind-ready: anyone who has operated outside around Lethbridge knows the wind will find every weak guy line. Plan for it.

End-fed half-wave (EFHW): one long wire, a small matching box at the feed end, and a short coax run. Throw one end into a tree or up a telescoping pole and you’re on several bands with no tuner. It’s the most common portable antenna for good reason.
Linked dipole: a dipole with clip or banana-plug links that let you change bands by opening or closing the links. Very efficient and no tuner needed, but you have to walk out and change links to change bands.
Vertical on a tripod or spike: a telescoping whip or a short vertical with a few laid-out radials. Small footprint, good for low-angle signals, handy when there’s nothing to hang a wire from.
Magnetic loop: a small loop on a stand that tunes very sharply. It goes up anywhere, even on a picnic table, and rejects a lot of noise. The trade-off is narrow bandwidth and constant retuning.
Random wire with a tuner: a length of wire and a 9:1 unun or an automatic tuner. Not the most efficient, but it works on almost everything.

Upgraded HT antenna: a longer whip on your handheld often makes a bigger difference than more power.
Roll-up J-pole: made from twin-lead or ladder line, it rolls up in a pocket and hangs from any branch. Getting it up a few metres beats any rubber duck.
Mag-mount on a metal surface: a mobile mag-mount on a car roof, a truck canopy or even a cookie sheet gives you a proper ground plane anywhere.

Telescoping fibreglass pole: a 7 to 10 m pole holds a wire end high and packs to under a metre. Use a drive-on mount or strap it to a trailer hitch or fence post.
Throw line: a weighted throw bag and thin line gets wire into trees. Always clear the area before you throw.
Guying: three light guy lines at about 120 degrees keep a mast standing in a gust. Use bright line so nobody walks into it.

Practise setting up in the yard before the trip. You’ll find the missing connector at home, not 200 km away.
Carry a small antenna analyzer or use your radio’s SWR meter to check before you transmit.
Keep coax runs short. Portable is usually low power, and every dB of loss matters more.
Pack a repair kit: spare wire, a connector or two, electrical tape and a knife.
