Can anyone point me to a website where a home built 70 cm reflectometer
or 70 cm field strength meter can be built -- not using surface mount
components. Thanks.


How about an SWR meter with no surface mount components? See:

Have fun!

Thanks for that. I really want to emulate a throughline (like the Bird 43 I
once had) and am thinking more in the terms of a stripline on PCB (using
BNC), with parallel lines to sniff the RF and diodes to convert for the
meters. But what I'm usure of is the sort of dimensions I should use for 70
cms, and wther these are critical. How long should the stripline be, what
spacing and so on, so that it doesn't in itself introduce errors and
misleading results. The sort of thing I would imagine would be in the ARRL
handbook, but I want to avoid the expense of buying the book if it's not in
there at all. BTW, most of the designs I've seen are HF or for up to 2
meters at the highest. I specifically want 70 cms, 435 MHz to be exact.
