Re: J-pole portable antenna

Wire Jpoles
That ARRL article came out just as I got my license and I had a new dual band HT. I built the antenna and it worked. Later when I borrowed an SWR meter I found that the antenna was way off, about 4:1 SWR. I now make wire jpoles with a piece of 450 ohm ladder line about 19" long and a half wave single wire attached to one side of the ladder line. It does work well on both bands as checked by an antenna analyzer. I can post dimensions if anyone is interested.

The issue is not that of "broad," being almost a 3rd harmonic of 2 meters. This generally applies to any antenna. Look at the geometry of the standing waves.

Re: J-pole portable antenna

Dale Putnam
 

I've built 6m & 2m J-poles, and used the Arrow. The Arrow is a whole lot easier, less time and fuss, to set up and use. About as plug and play as can be.

I've spent many hours building 2 & 6 m J poles, that's a fun way to spend a few days, setting up a 2 in dia 6 m J-pole. The 2 m is a little easier, mostly because the size. I used 3/4 in copper tubing, and plexiglass. Works well.. but it took a couple days fiddling around to gather all the parts, pieces, fit and tuning. The Arrow took 15 minutes to be on the air.

  They both talked the same.

  Your choice.


Have a great day,

Re: LNR Precision MTR-B

Colin Evans
 

The MTR5B doesn't come with a rotary encoder. There is very little space inside the case, I think it would be a struggle to squeeze in a rotary encoder.

EBay is flooded with encoders - the bog standard variety is fine - the type sold for Arduino experiments. There's a difference in the resolution - number of pulses per one rotation - all will work. I think I used an encoder with 20 ppr (pulses per rotation) for an MTR that I built.

To be honest, whilst the rotary encoder on the MTR-5B worked fine, I felt it added little to the operating experience. Using the up/down buttons, with fast and slow tuning rates, works great! My own MTR5B was built without the encoder, I don't miss it and I value the smaller case and lower weight.

My MTR5B was built from the kit - so case is home brewed. Will try to attach a picture of a rig with encoder.

Please bring your for sale gear along. There is always table space that can be shared. We will work it out.

The other week I signed up for my first Ozarkcon!

Got the hotel & banquet but Swap tables were all full up.


If anyone is interested in sharing table space, I have a several built & unbuilt QRP kits that I could bring and help free up some shelf space for other projects.


Thanks - Dave, N4ELM
