Ham Radio-Best Antenna Analyzer for The Money - Top 5 Analyzer of 2019




Ham Radio-Best Antenna Analyzer for The Money - Top 5 Analyzer of 2019.  Many have been asking what I recommend when the question arises about analyzers for checking aerial resonance etc.

I personally use the MFJ 269C, an analyzer was the sort of ham radio test equipment which I didn't think I would need, I would test aerial resonance by the cut and prune method which eventually got my aerial to the part of the band that I was interested in.

The MFJ-269 has changed the task of not only finding out exactly where my aerials are resonant it gives a visual indication in a digital readout of the actual frequency and of course the SWR reading.

The test equipment also indicates if the aerial is capacitive or inductive using the J-notation formulae, this is very useful if you are building matching devices, you can calculate how much more inductance or capacitance needed to resonant you're aerial.

The analyzer has a wide band which will help you with the common HF and VHF ham radio frequencies, the range covers 530Khz through to 230 Mhz, making it ideal for check two-meter aerials whether they are vertical or yagi arrays, using the MFJ 269 simplifies the process of tuning to get to as near 1:1 match as possible.

I do like the fact that it is fully portable due to the internal power source, you can take it anywhere, down the garden to check your vertical or dipole aerial.

Another very useful feature for someone who builds and aligns transceivers whether they are kits of ex PMR transceivers is the built-in frequency counter.

It's easy to simply set the dial and tune in a frequency just like your transceiver or receiver-many Short Wave Listeners are finding they can accurately build aerials to give the best reception due to correct matching using the MFJ-269. A good friend uses his analyzer to check the resonance of home build Yagi aerials before he acquired this piece of test gear it was a case of guessing if they were centered on the frequency of interest.

I use my MFJ on a regular basis for checking the match from end-fed aerials, or homemade traps, it takes all the guesswork out of the building process, RF networks can be easily checked without applying power.

Ham Radio-Which digital DMR radio can you use as a digital scanner?. Thank you for asking which DMR transceiver can be used at a scanner too, I found this video to answer your questions-the one that does the job that you are enquiring about, its the Anytone 868

Ham radio digital communication is increasing each day and it's a great way for the radio ham who no can longer erect dipoles for HF frequencies due to environmental laws or for the older generation who live in dwellings which restrict outside aerials.


You need a DMR identity code which you must apply for and insert into your Digital mobile radio to do this visit this link

For a list of DMR repeater s world-wide please visit this link

There are many pieces of equipment on the market to connect you and your transceiver to the Digital Ham radio networks, this link will help you 

I personally have used the D-VAP for D-star digital networks which worked very well, however, with the pace of technology in general along comes a digital access point which will probably become a classic, the openspot2, click this link for details  A super access point allowing cross-mode applications using one digital ham radio transceiver.

Thank you for your question about ham radio, I hope you find this page useful? please stay safe during the coronavirus. 73 de John G4YDM
