+I've recently purchased the famous chinese MX-P50M 45W amplifier as an addition to the X5105 for portable use. The amp is small, lightweight and does a decent job but I did not like the SO-239 sockets. I also did not like that there is a PTT cable permanently attached to the amplifier. This post describes briefly the steps to modify it to BNC and a dedicated PTT jack.
+
+The MX-P50M before the modification:

+
+After opening the case, I desoldered the PL sockets, removed the backplate, removed the sockets and replaced them with BNC sockets. The BNC sockets are mounted with screws which required drilling four 2,5mm holes for each one.

+
+In the above picture, the 3,5mm headphone jack can be seen, which will be used for triggering PTT via the transceiver.
+
+This is how the amplifier looks assembled but still opened:

+
+I've also replaced the original cable gland with a 3D printed one. You can find the design [here](https://www.thingiverse.com/thing:5264517).

+
+Since my old and proven antenna is only resonant on 20m and I did not like the fact, that the mast does not fit into any backpack, I decided to give the PAC-12 antenna system a go. I've ordered the following from Aliexpress:
+
+ * [5,6m long stainless steel whip](https://www.aliexpress.com/item/1005004662439855.html)
+ * earth spike with feed point (part of the set linked above)
+ * [radials](https://www.aliexpress.com/item/1005004552316570.html)
+ * [coil for 40m band](https://www.aliexpress.com/item/1005004758022020.html)
+
+All in all the antenna system cost me ~100 EUR.
+
+The antenna together with the X5105 for scale:

+
+The coil for 40m:

+
+This is how the antenna looks when deployed:

+
+## Protective Cover
+
+The earth spike is very pointed and might damage the backpack or other carried items. I've designed a 3D printable protective cover for it that also includes a winder for the radials. You can download it at [Thingiverse](https://www.thingiverse.com/thing:5736912).

+
+## Real World Test
+
+A first test of the antenna during my POTA activation of DA-0221 gave me very nice results (Xiegu X5105 + MX-P50M, 40m/20m/17m/15m):
+ 
+![image](/img/pac12-7.jpg)
+
+## Verdict
+
+I like it a lot! Which is convincing to me:
+
+ * fits into a backpack or can be held via MOLLE system
+ * no supports like a bench, table or tree needed. The antenna supports itself
+ * no coil needed for a quarterwave vertical for 20m or higher
+ * no complicated tuning via adjustable coil necessary. The antenna is simply pushed in or out.
+
+The whip seems quite solid but it can be damaged easily when improperly handled. This is why I've ordered a spare whip - just in case.
+
+Finally a picture with the antenna attached to the backpack using the MOLLE system:
