Hi,
I recently ordered and received the MP-1 antenna from W6MMA.
I read a lot about this antenna before ordering.. Some people do not
like it, some people do... And the good result depends on how people
experiment and use this antenna.
A few points that make me choose this antenna:
- I have a Buddipole, and they use the same threading, so parts of one
antenna can fit on the other and vice versa.
===) The combination of those two antenna makes an excellent
experimental kit like LEGO blocks!!! (==
- MP-1 is a very small kit. For a backpacker like me, weight, space
requirement, etc...
- The quality of construction of this antenna is almost as good as the
Buddipole.
One thing that is very important, if you use 80M coil option on the
MP-1..... don't even think to use the radial kit that normally comes
with the antenna.....
You must build another radial kit. I built one using cheap #18 AWG twin
speaker wires. Do 2 wires of 33 feet each, splice the two wires to
separate each wire. So you will have a total of 4 wires of 33 feet
each. Using a cable terminator, attach the 4 wires to the radial
terminal on the base on the MP-1 like before. Deploy the radial in a
star pattern... like a big X. Note that the use of a MFJ antenna
analyzer is really recommended to fine tune the antenna and to save a
lot of "AAARRRGHHH" time!!!
The transmit and receive gain is greatly improved !!! 33 feet is
approximatively 1/4 wave lenght of a 80M antenna based on frequency
3.750 Mhz....
So the kit is enough compact to fit in your K2 case.
