Some input
I use my meter to check from time to time to verify all is well.
This link has info on the meters
http://www.eham.net/reviews/products/40?ehamsid=a9efc7e8e58a376ce24c0118effd4579
The one I use is an MFJ-862 It has 2 needles for Forward and Reflected and will read watts for both. This is a low price unit, definately not a high, but had OK reviews. I have no idea if one can still buy it?

Yep, still available...(a little more than you probably paid for it):

OOPS! Stubbed my toe on that one. The price I latched onto
was for the DC power supply, the instrument itself sells for
about $70.

I found one offered here:
http://tinyurl.com/6m8zrru
Given it's rather complex set of features
(rear panel calibration pots) and low
price ($16) I'm wondering if they don't
have an inventory that they'd REALLY like
to get rid of.
MFJ is usually pretty good stuff and this
item does claim to cover VHF but I'm not
convinced that this is a good buy. I'm
tempted to order one at this price just to
take it apart for a looksee . . .
If you'd like to compare your personal item
with a set of BIRD measurements, I'd be pleased
to do the work. I'll pay return postage.

MFJ-862 Reviews
http://www.eham.net/reviews/detail/4367
Cannot remember what I paid back when. Withouit a long search looks like $65-70 is the going price
I bought it to cover my mobiles 144/220/440 MGHz and of course that includes the aviation band.
Ok for the 5 watt as well as my 50 watt units.

- Frank |
Probably not guaranteed to published specifications
but still useful. There was some discussion a few
weeks back about suitability of the LO Band (3-30
Mhz) devices being used at VHF. Typically devices
like this:
[img]cid:.0[/img]
These do perform as advertised in the 3-30 Mhz
range but tend to run off into the weeds at 4x
the top design frequency.
On the other hand, the MFJ862 used at 108-135
(full range aviation) is still at 75% of lower
end of 144 ham band. Maybe not quite as accurate
with respect to absolute readings but still
a good indicator of performance and useful for
finding frequency of lowest SWR.
For about the same $ you can pick up one of these
http://tinyurl.com/6pjbckd
which is designed for our particular frequencies
of interest.
On the other hand, there are some DIY options too.
Take a look at this article:
http://tinyurl.com/7dmupav
This DIY project is tailored to the 2.5 GHz range
for WiFi work but the same technique can be easily
adapted to lower frequencies.
Here's another one.
http://tinyurl.com/83e5u2q
All it takes is $time$ and patience . . . but
it can be fun . . .

Many thanks Bob.
That's extremely helpful.
You're a true gentleman!

I’ve used MFJ for years with no problems... HF and VHF.
