Look out lengths of RG174 at hamfests with a connector attached. Cut the cable down to 30 mm and carefully remove some of the outer and insulation. Solder the braid and centre conductor to make a short. Slip a coloured piece of heat shrink over the coax tail. You can put a thin cord under the heat shrink. Then apply hot air and shrink. You can tie the new short to your antenna using the cord. Make a spare and keep in your rucksack, just in case
Matt, I was going to write this but you’ve done it for me.
Trying not to lose small but valuable items at the summit can be a nightmare [I’m sure this could be a reflector topic in its own right]. More than twice my precious [and now no longer replaceable] Palm Pico twin paddle key has fallen down between a gap in the summit rocks whilst taking out of its storage bag.
I own the same antenna, and have experienced the (inevitable–?) loss of the cap.
I like VK3AFW’s solution, but what I did (after creating my own shorted SMA connector) is along the lines of MM0FMF’s recommendation. I used some very strong fishing line wrapped around the connector’s stem and super/krazy-glued into place. the other end is glued and taped to a small circular velcro/hook and loop pad, with the companion pad attached to the gray oblong. When I remove the SMA cap, it just dangles from the velcro closure. There is enough slack in the fish line to place the cap in position for 20/40.
I agree that putting such small items in pockets isn’t really effective; I’ve lost more gear that way! And in winter it can be a real pain trying to do something like that with gloves on.
Of course, there is another solution, one that is ideal for the indolent – if you have a good tuner, just leave the SMA connector in place and use the tuner on 30M. I confess to committing that sin quite frequently. ;-).
This was my default HF antenna for the last 3 years (then sold by LNR Precision) and occasionally I too would let the great internal ATU in my KX2 do the business for 30m rather than jump up and get the 30m stub off [which was often higher than I could reach].
In recent months my default antenna is a Chameleon MPAS Lite vertical so now I can just sit there and press the rig’s ATU button to switch between bands. And with gloves on it’s much less fiddly to put up and take down in cold weather.
