[Milsurplus] 4242-MK I

[B. Smith]

The 4242 is described on Shakespeares web page. They are listed as a "no 
tune" antenna and a 3.5 to 1 SWR over the 30 to 108 Mc range.     3.5 to 1 
is not a  real problem with  feed line losses   due to the short feed line 
length.

The mount shown appears to be for the AT1011 also on the web page.

| Hi there. I have a Shakespeare 4242 MK-1 antenna that I believe is for
| SINCGARS radios (ie PRC-25 etc).  My understanding is that this is a
| "broadband" antenna that does not require tuning for the range of singcars
| (forget the exact range, but it covers 6m).  I also believe this is a
| vertical dipole. Can someone confirm?
|
|
|
| The first mast section seems to have a "inside" conductor. Here is a 
photo.

| However, the base does not seem to have a mating connector. Is it 
possible,
| that the base and the mast are from different sets? Maybe they cannot work
| together?

|
| Also, does anyone know if there are any matching components or anything
| inside the base? I was thinking of using the base to try to mount a
| mast/whip for HF. Does anyone know if there are any low pass or baluns or
| anything inside the base I should watch out for?
