    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

Flexible (long) wire antenna for an HT? Does this exist?

Say you are backpacking in a remote area and would like to work a six or ten meter repeater off of an HT. Is there a suitable antenna on the market that would allow you to get out under those conditions at five watts? I think I've seen one somewhere before, but I cannot find one now. This would be something you could fold/roll up and stick in your pocket.

Yes, MFJ makes a longwire vhf longwire dipole for a talkie but you'd have to check their catalog for the model number.

The 2-Meter Roll-up J-pole Antenna and
Portable Roll-Up 2-Meter J-Pole Antenna are examples of 2 meter J-poles made out of 300 ohm twinlead.

The rest of the antenna is a suitable length of coax and some string or fishline. Throw a rock or stick attached to the fishline over a suitable branch. Tie the line to the j-pole, pull it up into the air several feet and transmit away.

I have made several twinlead J-poles for the 157MHz marine band and 160MHz railroad band and have found that they have better performance than a dipole. That is a bit surprising, since a J-pole antenna is simply a 1/2 wave dipole end fed via a 1/4 wavelength matching section.

It doesn't matter if it's connected to an HT or some other radio, a "long wire", or probably more accurately, a random wire antenna can certainly be made to work. Since how that wire will be run/mounted will make a difference in it's usability, figure on being able to tune it in some way.
Also figure on providing a ground, or the 'other half' of that antenna, that's going to be a necessity. If nothing else, and equal length of wire laid on the ground can work. A typical HT uses the radio's chassis and the one holding that HT as it's 'ground', which is never going to be all that 'good'.
All kinds of choices for a portable antenna, guess it just depends on how big your pockets are...

Some definitions;
Longwire: typically at least two wave lengths long at the frequency of use.
Randomwire: typically at least a 1/4 wave length long and more.
'Chunker': what you tie on the end of that wire/cord to throw something over something else.
'Chunkee': the one doing that chunking.
Frustration: typical state of the one doing that chunking or antenna using.
Expectations: what that @#$ antenna was supposed to do!
